There are two method of FM generation:

i) Direct method

ii) Indirect method (Armstrong method)

Indirect method (Armstrong method)

  • In this method, high frequency stability can be obtained because we can use crystal oscillator.

  • Armstrong method of FM generation is the indirect method because the modulating signal directly varies the …
