A pure note can be represented as y(t) = Asin(2pft), 72 partial differential equations where A is the amplitude, f is the frequency in hertz (Hz), and t is time in seconds. The amplitude is related to the volume of the sound. ... So, we should account for shifted sine functions in the general sum. Of course, we would then need to determine the ...
