For the most part, you won’t notice a difference

What does am and FM mean in AM/FM?

“am” and “fm” are the abbreviations for amplitude modulation and frequency modulation, the two main types of radio technology. In an analog radio, the signal is sent as a continuous wave, varying the amplitude (loudness) to represent sound and the frequency to represent pitch. In contrast, in a digital radio, the signal is encoded in a series of 1s and 0s — the “ones” and “zeros” of the digital
