From the given specifications, determine the value of voltage gain magnitude of first order and second order high pass butterworth filter? Pass band voltage gain=2; Low cut-off frequency= 1kHz; Input frequency=500Hz.

From the given specifications, determine the value of voltage gain magnitude of first order and second order high pass butterworth filter? Pass band voltage gain=2; Low cut-off frequency= 1kHz; Input frequency=500Hz. Correct Answer First order high pass filter =-0.9688dB , Second order high pass filter=-6.28dB

For first order high pass filter, |VO/Vin|=AF ×(f/fL) / =(2×(500Hz/1kHz)) /√ => |VO/Vin| = 1/1.118= 0.8944 =20log(0.8944) =-0.9686dB. For second order high pass filter, |VO/Vin|=AF / =2/√ =>|VO/Vin|=2/4.123= =0.4851 = 20log(0.4851) = -6.28dB.
