Given the lower and higher cut-off frequency of a band-pass filter are 2.5kHz and 10kHz. Determine its bandwidth.
A. 750 Hz
B. 7500 Hz
C. 75000 Hz
D. None of the mentioned
Answer:A
Given the lower and higher cut-off frequency of a band-pass filter are 2.5kHz and 10kHz. Determine its bandwidth.
A. 750 Hz B. 7500 Hz C. 75000 Hz D. None of the mentioned
Explanation: Bandwidth of a band-pass filter is Bandwidth= fH– fL=10kHz-2.5kHz=7.5kHz=7500Hz. 4. In which filter the output and input voltages are equal in amplitude for all frequencies?
