(c) An FM transmitter has the block diagram shown in Figure Q2(a). The audio frequency response is flat over the 20 Hz to 15 kHz audio band. The FM output signal is to have a carrier frequency of 100.1 MHz and peak deviation of 75 kHz. Find the frequency deviation and the output frequency required for the bandpass filter. 11. iii. Calculate the frequency, fo of the oscillator. What is the required peak deviation capability of the FM exciter? - 12- SULIT
FM exciter fc = 5 MHz Oscillator fo = ? (BEKC 2453) Bandpass filter Figure Q2(a) x 8 Frequency multiplier Class C amplifier SULIT FM output (6 marks) [25 marks]
