2. Consider the frequency response of a bandpass filter in Figure Q2. Determine each of the following:
(a) By using a first-order filter for each type of filter, design the appropriate circuit. Use the values of RFLP = RFLP = 560Ω, CHP = 0.047µF and CLP = 0.022µF.
(b) Determine the bandwidth of the filter.
(c) State the value of the center frequency, fo .
