1.	Sample and hold circuit is a _______ circuit.(a) Analog device(b) Digital device(c) Both analog and digital(d) Neither analog nor digitalThis question was addressed to me in a job interview.The question is from Analog to Digital Converter in portion Sensors of IOT
Answer» Right answer is (a) Analog device Easy EXPLANATION: An input CIRCUIT called a SAMPLE and hold performs task, most cases by USING a capacitor to store the analog voltage at the input, and using an electronic switch or gate to DISCONNECT the capacitor from the input.
