Explanation: In all-pass filter, the output and input voltages are equal in amplitude for all frequencies. This filter passes all frequencies equally well and with phase shift and between the two function of frequency. 5. The gain of the first order low pass filter
A. Increases at the rate 20dB/decade
B. Increases at the rate 40dB/decade
C. Decreases at the rate 20dB/decade
D. Decreases at the rate 40dB/decade
