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