What is the difference between FM and AM radio?


Radio stations are comprised of various types of frequency. Frequency in this case refers to electromagnetic wave frequencies that are between 3 kHz to 300 GHz.


AM-This is a lower frequency and is also known as medium wave analogue or mono. It is the process of amplitude modulation. It was the original system to carry  sound over a radio signal and was prominent in being the basis for the later FM frequency.

FM-is a higher frequency overall and is also known as an analogue frequency. It was pioneered by Edwin Howard Armstrong and is generally considered a more efficient method of broadcasting radio to audiences. FM carried the template of the AM frequency and strengthened it.

DAB-stands for digital audio broadcasting audio , which is becoming increasingly popular.
