Fm generation methods
The FM modulator circuits used for generating FM signals can be divided into two categories such as: (i) The direct method or parameter variation method (ii) The Indirect method or the Armstrong method The classification of FM generation methods is shown below : See more In direct method or parameter variation method, the baseband or modulating signal directly modulates the carrier. The carrier signal is … See more In direct FM generation, the instantaneous frequency of the carrier is changed directly in proportion with the message signal. For this, a device called voltage controlled oscillator (VCO) is … See more The varactor diode FM modulator has been shown below in figure 3.
