Estimate the desired parameters and draw the block diagram of an
Armstrong indirect FM modulator to generate an FM carrier with a
carrier frequency of 102 MHz and Δ?=25 kHz based on following
constraint:
A narrow-band FM generator is available at a carrier frequency
200 KHz and Δ? is 12.2 Hz.
The local oscillator has an adjustable range of 9 MHz to 10
MHz.
There is bandpass filter with any center frequency.
And only doublers are available.
Note: After all calculations, the values of each parameter of the above method should be written on the block diagram.
