How does a simple radio receiver work?

A radio receiver is the opposite of a radio transmitter. It uses an antenna to capture radio waves, processes those waves to extract only those waves that are vibrating at the desired frequency, extracts the audio signals that were added to those waves, amplifies the audio signals, and finally plays them on a speaker.

What is FM transmitter and receiver?

The transmitters are those devices which is used to send frequency modulated wave through a band and the receivers are the devices which received modulated signal then after demodulation it gives us the original signal.

Why is AM radio so bad?

This isn’t the reason why AM sounds bad and FM sounds good. With AM radio, they’re allowed to carry by FCC regulations about 11Khz on each side of the AM carrier. So audio is decent, your car radio has narrow filters in it so you maybe only get about 5-6Khz audio bandwidth, making it sound muddy and low quality.
