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?
A. All-pass filter
B. High pass filter
C. Low pass filter
D. All of the mentioned
Answer:A
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?
A. All-pass filter B. High pass filter C. Low pass filter D. All of the mentioned
Explanation: In all-pass filter, the output and input voltages are equal in amplitude for all frequencies. This filter passes all frequencies equally well and with phase shift and between the two function of frequency. 5. The gain of the first order low pass filter
