#ADC and Oversampling in 14 minutes: How to get more bits out of Analog to Digital Converters
How to squeeze more bits of those physically available from an Analog to Digital Converter? #Microcontrollers such as the ATmega328 on Arduino boards often are equipped with an #ADC, but usually the on board ADC has a limited resolution.
For example the one available on the Mega32A or the Mega328 has 10 bits, which is not bad but it could be a problem if you want more precision.
In this presentation I show how Analog to Digital Converters work, what is the technique known as Oversampling and Decimation, what are the trade-offs, and a practical example that I made on a board similat to an #Arduino Nano and a network display.
It is a combination of electronics and computer engineering.
Complementary information, code and a web-app simulator is also available on my website.

    Hi... ¿How can I find information about that oscillator and pulse generator? Now I know I can simulate it in a computer program or built mine in house but in both cases if I want to model it mathematically I would have to measure... In resume: could somebody tell me where can I see theory about oscillator and pulse generator?

      While I don't have a specific answer right now, a good starting point is to understand the theory of operation. Some more information is available on the relative page on my website, but there is literature (I think it should be available online) that covers oscillators and other signal manipulation through logic gates. I have an old book titled "Elettronica Digitale" (don't remember the publisher though and AFAIK it's only in Italian) that provides good coverage on the topic. Maybe searching for a similar title you may find something.

    I wonder what to do in the situation faced by me? The two Neutrals from the two outputs 230 VAC of the Nitrox Inverter ( 3 KW - 24 V, SP - Hybrid _ by A.P.T. ) aren't allowed to be jointed! At my home the PE and the Neutral are NOT jointed! Neither the Solar Panels nor the Inverter is Grounded till now! The Inverter demands the two Neutrals to be isolated and afloat! I'm rather perplexed. Obviously the two Phases are certainly to be distributed isolated! The problem faced has been that either regular Load RCD or the Smart Load RCD have been in the habit of tripping off upon Grid On / Off since installation. Even sometimes the RCD on the Input to the Inverter also goes off! The reason: the wiring of my home has become leaky for sometimes. I've been curious about the Phase difference of the two outputs of the Inverter. Is there any way to examine it's two lines 230 VAC (RMS) each. Probably phase difference of 120° with about 460 VAC (RMS) that amounts to be ~ 651 VAC RMS, oh no, sorry I mean to say 650 VAC Peak ! Moreover, the grounding croc clips of the O-Scope share the same common ground! Is there any way to compare the 2 outputs, one 'Regular Load' and the other 'Smart Load' be visualized on single O-Scope screen with custom devised High Voltage Probe(s) X100 on single or Dual Channel OScope? Note: The Inverter trips the RCD's on bringing the the neutrals near each other. I've a plan to examine the phase relationship of the Regular and the Smart Output phases without putting any load on these. The OScope to be used is a Rechargable Battery Operated ( Floating ) DSO ’ZEEVEII DSO3D12’ I've seen your kind vlog on a ’DP’ Passive Differential Probe utilizing Dual Channels on an Oscilloscope for measuring High Voltage safely, safe for the Operator, the OScope and the Device Under Test DUT. Would you suggest me to use similar probe for the situation faced by me. I'm waiting for 2 Accessory DP4100 Probes X100. With afloat DSO, the Cric Clips of the 2 DP4100 X100 grounded to earth and the probes on the two phases? Wouldn't it be safe for me , the OScope and the electrical system? Awaiting your kind response!

    • @AccidentalScience
      @AccidentalScience 2 місяці тому

      You *must* have a single ground. I mean a grounded spike to which all grounding convey, including the PE line. Power the oscilloscope referencing to that ground. Then use a couple of active differential probes rated at not less than 1000V. The measurement must be performed knowing the procedures of how to handle high voltages and you must know what you're gonna do because this could be lethal! I won't take liabilities. On the oscilloscope use math functions to know the difference between the two AC sources. You mention 460V RMS and ~651V RMS ...I don't think this is correct starting from 230VAC RMS, I'm afraid you keep confusing RMS with peak and peak to peak. Oscilloscopes *always* display peak to peak voltages. For voltages out of phase you can't really use the root square of 2 to go back and forth RMS. About the problem you face with that inverter I have a similar issue with a hybrid solar inverter, made by Voltronic, China. I have had no chance to investigate the problem deeply enough but it seems the problem arises from the fact that the inverter must disconnect neutral from ground when running over the grid, and reconnect it to ground when running over solar panels and batteries (UPS mode). What you describe, two separate neutrals, seems quite weird but for those inverter designed to run on two phases grids (no neutral) that are in use in some corners of the world. It seems an interesting case.

    • @AccidentalScience

      First off thanks for commenting. Indeed your comment could be of help for others. It could be helpful because many could confuse some points that clearly I have taken for granted when they'd not ...that's the curse of people with experience :) The current value is correct: around 320uA @ 230VAC. So why it is correct? An oscilloscope do not take the RMS voltage but the peak(+DC) voltage, while it shows the peak to peak voltage. I know, this may arise even more confusion, but don't worry, follow me. Let's take a sine wave that you want to measure at the oscilloscope. The instrument will show the sine wave from a reference point that is the GND (ground) level. In respect to GND the alternate sinusoidal signal swings from zero to full positive; then back to zero (GND); then down to full negative and finally back to zero again, where the cycle start over again. So what you actually see on screen is a wave that swings from peak to peak. However what matters for the input circuit is the voltage peak as an absolute value, which is the maximum allowed voltage in respect to ground irrespective of the polarity. Indeed if we look at the specifications of an oscilloscope they tell us the maximum input voltage that is meant as peak+DC voltage. In other words it is the absolute maximum voltage, be it AC or DC. So speaking about a possible voltage to measure I took as a reference example 230VAC, the mains voltage in EU. Mains voltage is alwasy declared as RMS voltage. So, for a sine wave with a 230 RMS voltage, for the purpose of finding the voltage that the oscilloscope's input matter we need to find out the peak voltage. Which for such a sine wave is: 230 times the square root of two, or simply 230 * 1.41 = 324.3 Vpk. When we compute the current across a resistor usually we compute it as DC or peak value, rarely as RMS value. And since we want to know the voltage at the input of the oscilloscope we have to calculate the peak value. So the math is as follow: Input voltage 324 Vpk / (990Kohm + 10Kohm) = 324uA. Remember, the current flows through both resistors to GND. Now because we know the current, and because the same current flows on both resistors, we can compute the voltage across the 10K resistor: 324uA * 10K = 3.24Vpk. Notice we should also consider the input impedance of the oscilloscope which happens to be in parallel with the 10K resistor. Though since this impedance is about 1Mohm at DC (or at very low frequencies such as 50 or 60 Hz) it doesn't change much our computations: 1/ ((1/1M) + (1/10K)) = 9900 ohm, actually an added attenuation of 1% . The probe x1 change anything as it is just a chunk of wire. Now, about the safe usage of the instrument, understanding that you are not that experienced, I'd recommend you to avoid taking measurements from mains. Instead use it to make measurements of small voltages of devices fully insulated from mains. In such a case it is quite safe to use in any condition. I never heard of that brand/model of oscilloscope, BTW. Hope this will be helpful. P.s. Thanks for love. Love+Peace.

      @@AccidentalScience I got your point! For all practical purposes, regarding AC voltage or current we talk about it's effective value, the root mean square RMS value that is equivalent to its counterpart DC's heating effect. It's the peak value of the AC V or C 'times' the Inverse of Square Root of 2 = 0.7071 In true measurement one has to consider the Peak Voltage or Current of the AC that's RMS value times √2=1.4142. So it would be around 325 uA. This has to be accommodated resistance and capacitance calculation. I'm grateful for reminding me!

    Dear Accidental Scientist, I'm happy to find your channel by accident! I myself happened to be an accidental scientist in lifelong apprenticeship! I'm interested in making ones home less prone to surges and transients produced by grid in and off and from environmental forces. Thank you for your vlog introducing us how the phenomenon of EMP can affect the electronics around us!
