2) One application of Low-pass filter is noise reduction. However, it has adverse effect on the image edges and may cause Ring effect. To mitigate the aforementioned issues, Butterworth and Gaussian filters have been proposed. Use the image below and apply the following filters. a) Apply Ideal low-pass filter and change its parameters and explain the results on the image edges. b) Apply Butterworth low-pass filter and change its parameters to compare the results with the ideal filter. c) Apply...

Design a parallel RLC band-pass filter to have the nominal center frequency f0 = 280 kHz and the 3dB bandwidth B = 7.9 kHz. Use only single, standard-valued components: 5% resistors, 10% capacitors and 10% IMS-5WD-40 inductors. Assume that inductor's Q is constant in the frequency range [0.1 - 1.0]ft, where ft is the 'TEST FREQUENCY Q' given in the IMS-5WD-40 data sheet. L = C = R =

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...
