Question: 4 . 9 - 2 Design ( the block diagram of ) an Armstrong indirect FM modulator to generate an FM carrier with a carrier

4.9-2 Design (the block diagram of) an Armstrong indirect FM modulator to generate an FM carrier
with a carrier frequency of 96 MHz and \Delta f=20kHz. A narrowband FM generator with
f_(c)=200kHz and adjustable \Delta f in the range of 9 to 10 Hz is available. The stockroom also
has an oscillator with adjustable frequency in the range of 9 to 10 MHz . There are bandpass
filters with any center frequency, and only frequency doublers are available. also make a block daigram in answer
