Estimate the desired parameters and draw the block diagram of anArmstrong indirect FM modulator to generate an FM carrier with acarrier frequency of 102 MHz and Δ?=25 kHz based on followingconstraint:
 A narrow-band FM generator is available at a carrier frequency200 KHz and Δ? is 12.2 Hz.
ï‚· The local oscillator has an adjustable range of 9 MHz to 10MHz.
ï‚· There is bandpass filter with any center frequency.
ï‚· And only doublers are available.
Note: After all calculations, the values of each parameter ofthe above method should be written on the block diagram.
