Problem 4. (6 marks) You are required to design a third-order Butterworth bandpass filter using ideal operational (6) Passband gain of 12 dB. (i) Lower cutoff frequency, f 6000 Hz. (ii) Upper cutoff frequency, u 12000 Hz. You are constrained to using 1 k? resistors in the lowpass filter and 10 nF capacitors in the highpass filter.

3.2 Simple Bandpass Filter Design The L-point averaging filter is a lowpass filter. Its passband width is controlled by L, being inversely proportional to L. In fact, you can use the GUI altidemo to view the frequency response for different averagers and measure the passband widths. It is also possible to create a filter whose passband is centered around some frequency other than zero. One simple way to do this is to define the impulse response of an L-point FIR...
Design a low pass filter with a cutoff frequency of 1 kHz +/- 100 Hz and a gain of 16.0 dB +/- 1.0 dB in the passband. The R2 and C components of the filter control the cutoff frequency, and are inversely proportional to the cutoff frequency. So decreasing the resistance or capacitance will increase the cutoff frequency. The R1 and Rf components determine the gain of the amplifier. Increasing the value of Rf will increase the gain. Increasing the...
