Design an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 89.5 $\mathrm{MHz}$ and $\Delta \mathrm{f}=51.2\mathrm{kHz}$. A narrowband $\mathrm{FM}$ generator with $f_c=10\mathrm{kHz}$ and adjustable $\Delta \mathrm{f}=20^{\sim }30\mathrm{Hz}$ is available. The stockroom also has an oscillator with adjustable frequency in the range of 1 to $1.2\mathrm{MHz}$. There are bandpass filters with any center frequency, and only frequency doublers are available. Sketch a block diagram of your design that uses the least number of frequency doublers, clearly indicating the value and location of the oscillator, location of the band-pass filter as well as the center frequency and the peak frequency deviation at the output of each stage in your design. Write a design report of your project. It should include the block diagram of your design and detail explanation of your design process and calculations. Attach this page at the beginning of the report.
