Q. Explain about Frequency Shift Keying?
In this scheme frequency of the carrier signal is changed according to the data. Transmitter sends different frequencies for a "I" than for a "0" as displayed in Figure. Disadvantages of this technique are that again (as it was with amplitude modulation) the rate of frequency changes is limited by bandwidth of the line and that distortion caused by the lines makes detection even harder than amplitude modulation.
