radio communications: am and fm
... The noise added to the FM signal by the receiver will also be occupying the same band as the FM signal itself. Such bandpass noise will corrupt the instantaneous value of the FM signal, and thus corrupt the zero-crossings. It is the corruption of the zero-crossings that will affect the demodulated s ...

Angle Modulation Part 2
... Angle modulation is resistant to propagation-induced selective fading since amplitude variations are unimportant and are removed at the receiver using a limiting circuit. Angle modulation is very effective in rejecting interference. (minimizes the effect of noise). Angle modulation allows the use of ...

Superheterodyne receiver
In electronics, a superheterodyne receiver (often shortened to superhet) uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original radio carrier frequency. It was invented by US engineer Edwin Armstrong in 1918 during World War I. Virtually all modern radio receivers use the superheterodyne principle. At the cost of an extra frequency converter stage, the superheterodyne receiver provides superior selectivity and sensitivity compared with simpler designs.
