a) The filter of a diode detector circuit filters out 521.2MHz and 535.8MHz. Find the components of the amplitude modulated wave (carrier frequency, modulating frequency, and upper and lower sideband frequencies). b) For a filter method SSB transmitter, what should be the center frequency of the bandpass filter to select the (a) upper and (b) lower sideband given an operating frequency of 7.26MHz and a voice frequency range of 350 to 3200 Hz? c) Given a varactor modulator, how much will the resonant frequency change if the depletion region of the varactor decreases by 20%?
