In an FM broadcast transmitter, the carrier signal is being deviated between 103.505MHz and 103.495MHz, 1200 times/sec by a 5V sinusoid. How to prove that the percent modulation is 6.67%
Starting from the general expression of the frequency modulated wave, find out the expression of narrow band FM (NBFM).
An FM signal has a deviation of 3 kHz and a modulating frequency of 1 kHz. Its total power is 5 W, developed across a 50 2 resistive load. The carrier fre- quency is 160 MHz. (a) Calculate the RMS signal voltage. (b) Calculate the RMS voltage at the carrier frequency and each of the first three sets of sidebands. (c) Calculate the frequency of each sideband for the first three sideband pairs. es Falerna avlop (d) Calculate the power at the carrier frequency, and in each sideband, for the first three pairs.
