Droop rate:

The rate of change of the output voltage when the control signal is in the hold state.

The droop rate is due to leakage currents flowing on or off the hold capacitor and therefore the droop rate is less for large capacitors.

dVH/dt = Ileakage/CH

VH: Hold voltage

t: time

I: current

C: capacitor

Why you use sample and hold?

The purpose of this circuit is to hold the analogue value steady for a short time while the converter or other following system performs some operation that takes a little time.


Explain the purpose of the simple and hold circuit in a computer controlled data acquisition system that uses a ADC?

I presume you mean "sample and hold"; to read a voltage an ADC takes a finite amount of time - if the voltage changes during that time, then a misreading can occur. The sample and hold keeps the voltage seen by the ADC constant during the reading time.

What effect does non-random sample have on what you can say about the results of a study?

It means that the results of the study cannot be claimed to hold for the entire population from which the sample was drawn. The researchers can only claim that their results hold for the individuals selected into their sample.
