My last semester syllabus is full of this ADC & DAC concept....I feel like if this video uploaded a little before...I would have preferred a little better for the exams...but thank u so much for uploading this video...now I understand more about converters...tq sir...👍
I find it ironic that a channel that focuses on electronics always has its audio boosted to to the point that it is always clipping and horribly distorted.... please speak softer or turn the gain on your microphone down a bit
If you got any problem go learn from some paid courses.....he's teaching here for free and you're whining like a kid about something that isn't even that relevant
See the problem here is this channel's videos are often referenced in the paid course that I am indeed taking. It gets really frustrating when you're trying to prepare for exams when you're really pressed for time and just looking for a to the point and easy explanation of something and then all you can find is videos that are actually really unpleasant to listen to... we all have things that get to us. For some of us, that's audio like this. Furthermore, regarding the paid courses, RU-vid does pay, most content creators aren't doing it for charity, and I dont think asking someone to turn their gain down a bit is too much to ask for considering its such an easy thing to do.
Even when you shift the TF function to the left. The quantization error is still 1LSB as the resolution isn't changed and the smallest voltage that will be detected is still 1LSB.
Yeah... But The Continuously increasing or decreasing input signal is detected if it continuously increases or decreases by +0.5 or -0.5 which is better than detecting if it continuously increases or decreases by +1 or -1
Sir please explain ADC and DAC much more detail with corresponding waveforms. Use any one process as an example. Eg. (Analog) voice signal recording using tape record
if we increasing the bit then resolution decreases ig because when we take No of bits = 3 and FSR =10, resolution = 1.25V when we take No of bits =8 and FSR=10 , resolution= 0.039V where Resolution decreases in this case
Yes, that’s true that the minimum voltage that can be resolved by the ADC reduces, but in a way it’s resolving power increases and typically the adc with higher resolving capacity are said to be high resolution adc. I hope, it will clear your doubt.

pls tell me that how adc and dac are connected in the circuit and what are the process which the signal has to undergo in case of conversion from analog to digital and as well as from digital to analog. One more thing what is the structure of these ADCs and DACs and can we enhance the conversion process by using another device other than ADCs and DACs?
I tried to minimize it digitally as much as I can. But if I had gone further, it would have changed my voice texture too. So, I have minimized it as much as I can. But anyway, I will try to record it at quite time if possible.
The first step during the digitization is sampling. The signal in time domain is continuous. We are doing the digitization at the discrete intervals. Using sample and hold circuit, we are sampling the input signal at the discrete interval. After the sampling, the next step is the quantization.
Nopes the resolutions is : Full Scale Voltage/2^N We divide the input into N intervals and assign a code to it. To get a clear idea, consider 2 bit ADC with 1V full scale range There will be 4 intervals (2^2=4) with a unique code for each interval as follows 00- 0-.25V 01- .26V- .5V 10- .51V-.75V 11- .76V- 1V So the resolution of this ADC will be .25V because that's the smallest change in input that it will detect
Hi, If I get across such integrated IC, I will definitely recommend you. But meanwhile you can go through this article. Which might be helpful to you in interfacing instrumentation amplifier with ADC. www.ti.com/lit/an/sbaa314/sbaa314.pdf
Regarding hi res audio...if the signal passes from digital to analog in high quality (flac 24 bit/96 khz), then from analog to digital, and then from digital to analog. will the queality of the signal be the same/better?. Digital audio player with its DAC - ADC - DAC/ AMP.? I wanto to use a DAP as audio source that can play lossles formats in hi res (24 bit/192 khz), and use other DAC of other divice that sounds better. The DAP doesn't have a digital audio output. So I want to conect the DAP to ADC and then the ADC to a DAC/AMP and get the best possible soumd coming from last DAC and the high resolution format (24bit/96khz).
Drive Model - DC1-S2011NB-A20CE1 PRESSURE SENSOR: SHNIEDRER BRAND XMLR010G0T75 0-10VOLTAGE , 0-10 BAR At present I have stored motor name plate details to VFD and at present the system runs @ 0 to 3.7 Bar Now , Please let me know how I can do the scaling from 0-10 Bar to 1.1- 3.4 Bar permanently. We put the scaling parameter P-35=700% and Offset parameter P-39=70 At this stage we closed the discharge valve. The pump started from 0 bar and reached to 3.7 Bar and stopped the pump as per the delay time. Then we opened the discharge valve and since the pressure reached to 0 Bar, pump started. After we close the valve. But the pressure reached only up to 2.7 Bar and pump runs continuously even when valve closed full and didn’t reached to 3.7 bar. How can we analyze the pump start and stop by setting parameter P-35 and P-39, is there any equation or like that
