True or False: The FM receivers output is relatively free of atmospheric and man-made noise.

The statement is true because Frequency Modulation (FM) receivers are designed to be largely immune to various forms of noise, including both atmospheric and man-made interference. FM encoding transmits information in the frequency of the carrier wave, which allows it to effectively distinguish between the desired signal and noise, since noise typically affects amplitude rather than frequency.

This is particularly important in radio communications, where external interferences can degrade the quality of the signal. The inherent characteristics of FM — such as its use of larger bandwidth and its ability to reject amplitude variations — help maintain a clear audio output even in environments with significant noise exposure. Thus, the FM receivers can provide a cleaner and more stable signal quality compared to amplitude modulation (AM) formats, resulting in the correct answer being that the output is indeed relatively free of such noise.
