R1 = R2,
C1 = C2,
So higher and lower cut-off frequencies are same.
C1 = C2,
So higher and lower cut-off frequencies are same.

It's simple.
Cutoff frequency = 1/2*I*R*C.
= 318.309 Hz.
Both frequencies will be same.
Cutoff frequency = 1/2*I*R*C.
= 318.309 Hz.
Both frequencies will be same.

For a high and low pass filter the cut-off frequencies are given out in the following way f(3db)=1/[RC*2π]
Hence the Fol = 318.3=Foh.
Hence the Fol = 318.3=Foh.
