AF= 218.3 =20log(218.3)= 46.78dB. 6. The pass band voltage gain of a second order low pass butterworth filter is
A. 1.586
B. 8.32
C. 0.586
D. 0.707
Answer:A
AF= 218.3 =20log(218.3)= 46.78dB. 6. The pass band voltage gain of a second order low pass butterworth filter is
A. 1.586 B. 8.32 C. 0.586 D. 0.707
Explanation: Second order low pass filter has a pass band voltage gain equal to 1.586 because of equal resistor and capacitor values. This gain is necessary to guarantee butterworth response. Sanfoundry Global Education & Learning Series – Linear Integrated Circuit.
