a) Derive the expression for the scaled transfer function for the filter designed in Problem 15.44.
b) Using the expression derived in (a), find the gain n = 6. (in decibels) at 40 Hz and 1000 Hz.
c) Do the values obtained in part (b) satisfy the filtering specifications given in Problem 15.44?
Problem 15.44
a) Design a broadband Butterworth band pass filter with a lower cutoff frequency of 200 Hz and an upper cutoff frequency of 2500 Hz. The pass band gain of the filter is 40 dB. The gain should be down at least 40 dB at 40 Hz and 12.5 kHz. Use 1 μF capacitors in the high-pass circuit and 25 kΩ resistors in the low-pass circuit.
b) Draw a circuit diagram of the filter and label all the components.
