List of top Electronics and Communication Engineering Questions on Filters

In a low pass filter as below, find the cut-off frequency for the following circuit. Given that \(R1=20\text{k}\Omega\), \(R2=25\text{k}\Omega\), \(C1=10\mu\text{F}\).
The bandwidth of a tuned circuit is
A signal is processed by a causal filter with transfer function \( G(s) \). For a distortion-free output signal waveform, \( G(s) \) must
