AM/FM broadcasting

• AM broadcasting is the process of radio broadcasting using amplitude modulation
• FM broadcasting is the process of radio broadcasting using frequency modulation

I don't remember ever having heard this explanation.

In German a different terminology is being used for radio broadcasting:

• UKW for Ultrakurzwelle, in English: VHF for very high frequency, popularly (but incorrectly) also FM
• KW for Kurzwelle, in English: SW for short wave or HF for high frequency
• MW for Mittelwelle, in English: MF for medium frequency, popularly (but incorrectly) also AM
• LW for Langwelle, in English: LowFER for Low-Frequency Experimental Radio
