(a) Design (the block diagram of) an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 98.1 MHz and Af 75 kHz. A narrowband FM generator is available at a carrier frequency of 100 kHz and a frequency deviation Af = 10 Hz. The stockroom also has an oscillator with an adjustable frequency in the range of 10 to 11 MHz There are also plenty of frequency doublers, triplers, and quintuplers. (b) Determine the tunable...
