Explanation: Quality factor of band-pass filter, Q =fc/bandwidth= 566/250=3.46. 4. Find the center frequency of wide band-pass filter
A. fc= √(fh ×fL)
B. fc= √(fh +fL)
C. fc= √(fh -fL)
D. fc= √(fh /fL)
Answer:A
Explanation: Quality factor of band-pass filter, Q =fc/bandwidth= 566/250=3.46. 4. Find the center frequency of wide band-pass filter
A. fc= √(fh ×fL) B. fc= √(fh +fL) C. fc= √(fh -fL) D. fc= √(fh /fL)
Explanation: In a wide band-pass filter, the product of high and low cut-off frequency is equal to the square of center frequency
