Solve Problem
- Expand the floowing periodic functio in a Fourier series.
- Expand the function
- Derive the approximate relationship (2.90) for the order n of an all-pole filter. What order normalized lowpass Butterworth filter will have an attenuation of at least 100 dB at 6 rad/s? Write the transfer function of the filter, and confirm that it does have the required attenuation.
- What order lowpass Butterworth filter will satisfy the following specifications?
a) Cutoff frequency at 2 Hz
b) At least 60 dB down at 8 Hz
- Find the transfer function of a highpass Butterworth filter to pass frequencies above 10 Hz. The stopband should be down at least 60 dB at 5 Hz. Plot the magnitude response and the phase response.
- Design a bandstop Butterworth filter with stopband from 100 to 125 Hz. The attenuation should be at least 20 dB at 105 and at 120 Hz. Plot the magnitude response and the phase response.
- Design a bandpass filter with the following characteristics. Then plot the magnitude response and the phase response. Plot the poles on the s-plane.
a) Passband 60 to 80 Hz
b) Passband ripple not to exceed 0.5 dB
c) Attenuation of at least 40 dB at 50 Hz and at 100 Hz
d) Gain set so that the maximum magnitude in the passband is unity.
