The input is constant amplitude of 2v from 0 to 0.1ms and from 0.1ms to 0.2ms. The output for each of these half periods will be ramp. Thus, the expected output is triangular wave. 8. What happens if the input frequency is kept lower than the frequency at which the gain is zero?
A. Circuit act like a perfect integrator
B. Circuit act like an inverting amplifier
C. Circuit act like a voltage follower
D. Circuit act like a differentiator
Answer:A

A. Circuit act like a perfect integrator B. Circuit act like an inverting amplifier C. Circuit act like a voltage follower D. Circuit act like a differentiator
Explanation: If the input frequency is lower that the lower frequency limit of the integrator (i.e. when gain = 0), there will be no integration results and the circuit act like a simple inverting amplifier. 9. Match the correct frequency range for integration. (Where f –> Input frequency and fa –> Lower frequency limit of integration)
