Question

Design a second order IIR Butterworth low pass digital filter with a cutoff frequency of 500 Hz and a sampling frequency of 10,000 Hz using bilinear transformation then find the following:

                       

1.       The output (response) due to the following inputs:
   1.             Sinusoidal signal with a frequency of 100Hz.
   2.             Sinusoidal signal with a frequency of 500Hz.
   3.             Sinusoidal signal with a frequency of 2000Hz.
