1. Is RC circuit a low-pass or high-pass filter?

2. What is rise time, fall time and delay time in RC circuit?

3. What is the time constant of a RC circuit? How to find its value by experiment?

4. How does the delay time change when there are more RC stages in RC circuit?

1. What is the concept of slew rate?

2. What is the output waveform of a voltage follower if the input is a square wave?

3. How would you experimentally measure the slew rate of a voltage follower?

4. What is open loop gain and close loop gain? What are the advantages of close loop gain?

5. How would you design a math equation like 2A+3B using basic opamp circuits?

Solution

1) RC circuit is a Low pass Filter that is it allows low frequency component in the input and blocks high frequency component,its time constant t=RC sec
