Problem 1. Design an active bandreject filter by combining 1* order high and low pass stages. Make the lower cutoff frequency 1500 Hz, the upper cutoff frequency 25000 Hz and the passband gain 6 dB. Use 50 nF capacitors. Do the following: a. Find the overall transfer function of the filter. b. Draw the circuit including component values. c. Use Matlab to draw the Bode plot of the filter. d. Calculate the filter gain (in dB) at the center frequency. If the lower cutoff frequency were increased to 3000 Hz, would the filter gain at the center frequency increase or decrease? Explain.
