Design a low pass filter with a cutoff frequency of 1 kHz +/- 100 Hz and...
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...
