WebExplanation: Direct method and indirect method are the methods used for generating FM signals. These methods are differentiated by the variation of the carrier frequency. advertisement. 8. In indirect method, the carrier frequency is directly varied in accordance with the input modulating signal. a) True b) False WebFrequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and computing.. In analog frequency modulation, such as radio broadcasting, of an audio signal representing voice or music, the instantaneous … 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. flints discount code
