1. Design an active-RC low-pass second order Chebyshev filter with a cutoff frequency of 1 kHz, a passband gain of 2 V/V and approximately 2 dB of ripple. If using Table I, use a capacitor value of 0.1 μF for C and C1. Choose appropriate, real resistor values. If applicable, make an excel worksheet showing the calculations required for the above design. Simulate this circuit for input AC amplitude of 1 V. Obtain an AC response plot of the output for a frequency range of 1 Hz to 100 kHz.
2. Design an active-RC low pass second order Butterworth filter for a cutoff frequency of 1 kHz, and a pass band gain of 2 V/V. If using Table I, use a capacitor value of 0.1 μF for C and C1. If applicable, make an excel worksheet showing the calculations required for the above design. Choose appropriate real resistor values for the designed circuit and simulate this circuit for input AC amplitude of 1 V. Obtain an AC response plot of the output for a frequency range of 1 Hz to 100 kHz.
