C12 (20 points)
A signal m(t) frequency modulates a 100 kHz carrier to produce the following narrow band FM signal:
Generate (block diagram design) the wideband FM signal q ,,, with a carrier frequency of 100 mHz and a (peak) frequency deviation of 75 kHz Assume that the following are available for the design.
1. frequency multipliers of any (integer) value
2. a local oscillator whose frequency can be turned to any value between 120 MHz to 500 MHz
3. An ideal bandpass filter with tunable center frequency and bandwidth
your block diagram design must clearly specify the carrier frequencies and frequency deviation at all logical points as well as the center frequency and bandwidth of the bandpass filter
