\[
\boxed{
\text{Increases gain but reduces bandwidth.}
}
\]

- Larger bandwidth
- Same bandwidth
- Smaller bandwidth
- Infinite bandwidth
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Recall the effect of cascading amplifier stages.
When amplifier stages are cascaded,
- the overall gain increases,
- the lower cut-off frequency increases,
- the upper cut-off frequency decreases.
Step 2: Determine the bandwidth. Since \[ \text{Bandwidth}=f_H-f_L, \] the overall bandwidth becomes smaller. Hence, \[ \boxed{\text{Smaller bandwidth}} \] Therefore, \[ \boxed{(C)} \] is the correct answer.
Step 2: Determine the bandwidth. Since \[ \text{Bandwidth}=f_H-f_L, \] the overall bandwidth becomes smaller. Hence, \[ \boxed{\text{Smaller bandwidth}} \] Therefore, \[ \boxed{(C)} \] is the correct answer.
