Web계속 (capture effect) 5. Despite the fact that FM has superior noise rejection qualities, noise still interferes with an FM signal. This is particularly true for the high-frequency … 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
WebIndirect 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 … WebIn the art there is known to be two general methods for generating frequency modulated signals, namely, indirect FM and direct FM. ... An FM transmitter using the frequency modulator of FIG. 2 as described is shown in FIG. 3.
