Raised cosine
WebbA special case of the Meyer scaling function is shown to coincide with the square root raised cosine (SRRC) communication pulse, provided the fractional excess bandwidth is bounded above by one third. This pulse is widely used in digital transmission ... WebbThe reason it’s called the raised-cosine filter is because the frequency domain when is a half-cycle of a cosine wave, raised up to sit on the x-axis. The equation that defines the …

It is commonly used in communications systems in pairs, where the transmitter first applies a root raised cosine filter, and then the receiver then applies a matched filter.
