This document discusses the design and components of an FM radio receiver. It includes sections on the introduction, block diagram, history, FM receiver design, basic apparatus used, simulation, and operating frequency range. The history section notes that the first radio receiver was developed in 1896 by Alexander Stepanovich Popov, based on electromagnetic waves proven to exist by James Clerk Maxwell in 1887. The FM receiver section explains that FM receivers utilize the superheterodyne principle at higher frequencies between 88-108 MHz, with a limiter to ensure a constant signal amplitude before detection and FM demodulators to convert frequency variations to amplitude variations at the output.

6. FM Receiver
• FM receivers, like AM receivers, utilize the super
heterodyne principle, but they operate at much
higher frequencies (88 - 108 MHz).
• A limiter is often used to ensure the received
signal is constant in amplitude before it enters
the detector.
• The FM demodulators must convert frequency
variations of the input signal into amplitude
variations at the output.
