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 about each element on this diagram.
