= [2/√(1+(1.2kHz/10kHz)2]×( 2.606) = 1.986×2.606 =5.17 =20log×(5.17) =14.28dB. 10. The quality factor of a wide band-pass filter can be
A. 12.6
B. 9.1
C. 14.2
D. 10.9
Answer:A
= [2/√(1+(1.2kHz/10kHz)2]×( 2.606) = 1.986×2.606 =5.17 =20log×(5.17) =14.28dB. 10. The quality factor of a wide band-pass filter can be
A. 12.6 B. 9.1 C. 14.2 D. 10.9
Explanation: A wide band-pass filter has quality factor less than 10. 11. Design a narrow band-pass filter, with fc=1kHz, Q= 13 and AF=10 (Take C=0.1µF)
