You are designing an Armstrong FM radio with a carrier frequency of 91.2MHz and frequency deviation between 40kHz and 45kHz. Your NBFM generates a FM signal with a carrier of 200kHz and the generated frequency deviation is 10Hz. The local oscillator can generate sinusoids with any frequency in the range of 10-12 MHz. Note that you can only use frequency doublers, and you have as many doublers as you need. Draw the block diagram of the FM transmitter. Give details...
