Is it true that a compactor ic chip or comparator circuit is jUST a two state output either on or off. The sample and hold circuit is not just off and on states or high and low states
Yes i know that, but is that what the circuit does that i posted?The HOLD button freezes the reading at the last recorded value.
That is what a sample and hold circuit is supposed to do in your application.
The output of the Op amp gets feedback back to the differential input, this is the sampled voltage right?so what would you guess is the input that is going to be sampled?
How is it subtracted? the differential amplifier compares the reference voltage to the sample voltage and subtracts them? at a gain of 1?It is a differential amplifier, so nothing is being compared, only subtracted.
So what is the difference between a comparator and a sample and hold circuit? they both subtract two signals and output the difference or a differential voltageGuess what a comparator does. It subtracts two signals.
I'm not understanding the differences , they are both comparing two signals and subtracting two signals.A comparator is not a sample and hold circuit.
A sample and hold circuit is not a comparator.
They are two different functions.
