Derivation of beat frequency

WebBoth the sum and difference frequencies are exploited in radio communication, forming the upper and lower sidebands and determining the transmitted bandwidth. When you say that the beat frequency is f 1 -f 2 rather than (f 1 -f 2 )/2, that requires some explanation. For the difference frequency you can just say that you get a minumum when the ... WebBeat frequency in physics means the difference in the frequency of two sound waves. Beats that we hear by our ears are the periodic and repeating fluctuation in sound. The study of properties of sound in physics is known as …
