SERIES
Low level cut off frequency fcl and High level cut off frequency fch is
fcl= 1/2
π
C1R1 = 106 Hz fch = 1/2
π
C2R2 = 1.1kHz
and , the gain of amplifier Gv is
Gv = R2/R1 = 20 dB.
Same as the band pass filter is constituted microphone signal input.
INPUT
R1=10k
C1=0.15μF
OUTPUT
R2=100k
C2=1500pF
