Answer : Sample and hold circuit is the important part of data converters (ADC and DAC). Sample and hold circuit is also called as track-and-hold circuit. Sample and hold circuit is use for sampling ... some time. Sample and hold circuit basically uses an analogue switch (like JFET) and capacitor.

Description : In a sample-and-hold circuit, the aperture time is (A) time required following a sample (B) time required for the switch to open (C) transition time interval between sample and hold (D) time from the hold command to the opening of the switch 

Description : Explain the function of sample and hold circuit by using op-amp.

Answer : sample and hold circuit by using op-amp The n-channel MOSFET is driven by a control voltage VC acts as a switch. The control voltage VC is applied to the gate of the MOSFET ... called sample period. The time period during which the voltage across capacitor is constant is called Hold period.

Description : Define Sample and hold period with reference to S/H circuit.

Answer : Sample Period:- The time period during which the voltage across the capacitor is equal to the input voltage is called sample period. Hold Period:- The time period during which the voltage across the capacitor is constant is called hold period.

Description : Sample -and -hold circuits in ADCs are designed to : - a) sample and hold the output of the binary counter during the conversion process b) stabilize theAD Cs threshold c) voltage ... d) signal during the conversion process sample and hold the ADC staircase waveform during the conversion process

Answer : Sample -and -hold circuits in ADCs are designed to : - voltage during the conversion process stabilize the input analog
