one of the problems with the armstrong method is that the frequency deviation—the amount of modulation—must be kept small to minimize distortion. the maximum deviation is a fraction of 1 kilohertz, but fm broadcast requires 75 kilohertz deviation and a typical fm voice channel deviation is 5 kilohertz. to solve this problem, armstrong multiplied the signal many times to a higher frequency to obtain the necessary deviation. for example, to generate an fm signal with 5 kilohertz deviation at 146.94 megahertz, the transmitter would generate a signal at 6.1225 megahertz with only 0.2 kilohertz deviation, and then multiply the signal 24 times.
