Direction: Round off your answers to three decimal places. 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%?

Urgent please!! 4.1. Assemble the low-pass filter circuit which is in Figure 3.1. Follow the instructions below step by step.a) Setup the signal generator so that it produces a sinusoidal waveform, with a peak to peak voltageof 10V. Use the oscilloscope to verify this.b) Use channel 1 of the oscilloscope to display Vin and Channel 2 to display Vout. You may needto set up the triggering function of scope, especially for the lower frequencies.c) Starting from 50 Hz, vary the frequency of the input signal up to 2500 Hz in a sufficient numberof steps. For each increment, note down the peak to peak voltage of the output for each frequency, and tableit to your laboratory report. Then, plot a graph of the amplitude of Vout against the frequency.d) From your graph, mark off 70.7% of your peak voltage, and note down the corresponding cutofffrequency, fc.e) The cut-off frequency can also be calculated by the circuit components R and C. Calculate andcompare it with your experimental result. 4.2.…
