AM/FM

What is AM/FM?

AM and FM are two different types of radio broadcasting technology. AM stands for Amplitude Modulation, while FM stands for Frequency Modulation. AM radio works by varying the amplitude, or height, of the radio waves to carry the audio signal.

The audio signal is impressed on the carrier wave by modulating its amplitude. AM radio is typically used for talk radio and news broadcasts. FM radio works by varying the frequency of the radio waves to carry the audio signal. The audio signal is impressed on the carrier wave by modulating its frequency. FM radio is typically used for music broadcasts, as it provides higher fidelity sound than AM radio. Both AM and FM radio signals can be received using a radio receiver, which includes a tuner and an antenna. The tuner selects the desired frequency or station, and the antenna receives the radio waves and converts them into an electrical signal that can be amplified and played through a speaker. Overall, AM and FM radio are two different broadcasting technologies that are used for different types of broadcasts. While AM radio is typically used for talk radio and news, FM radio is typically used for music broadcasts due to its higher fidelity sound.
