WebGeneration of FM Wave The FM modulator circuits used for generating FM signals can be divided into two categories such as: (i) The direct method or parameter variation …
WebThe Armstrong method begins by generating a carrier signal at a very low frequency, say 500 kilohertz. This frequency is below the AM broadcast band and much below the current FM broadcast band of 88 to 108 megahertz. This carrier signal is applied to two stages in the transmitter: a balanced modulator and a mixer. WebLECT-22: GENERATION OF FM WAVE (DIRECT & INDIRECT METHOD)
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.
