What is the stop band gain of a low pass filter with δS as the pass band attenuation?
A. -20log(1- δS)
B. -20log(δS)
C. 20log(δS)
D. 20log(1- δS)
Answer:A
What is the stop band gain of a low pass filter with δS as the pass band attenuation?
A. -20log(1- δS) B. -20log(δS) C. 20log(δS) D. 20log(1- δS)
Explanation: If δS is the stop band attenuation, then the stop band gain is given by the formula 20log(δS) .
