Hat Is Fm? How Does It Work? Explain The Difference Between Am And Fm? |
|
Answer» FM stands for Frequency Modulation which is an analog modulation scheme where frequency of the CARRIER signal is varied ACCORDING to the MESSAGE signal unlike amplitude in AM. For a binary signal which has only two possibilities – 0 and 1, two carriers (with different frequencies) are used for denoting 0 and 1. It is used for audio signals for example Radio ETC. which OPERATE in the frequency range of 88-108 MHz.
