A Raised Cosine Filter is a type of filter commonly used in computer science that has an adjustable bandwidth controlled by the "roll off" factor. It is designed to shape the frequency spectrum of a signal to meet specific requirements, with a trade-off of requiring more frequency spectrum to...
Characteristics of the raised cosine receive filter are the same as in theRaised Cosine Receive Filterblock, except that for transmit filtering, the input response length of the filter depends on the value of theOutput samples per symbolparameter. ...

To control ISI, control has to be exercised over the pulse shape in the overall system, known as pulse shaping. The mostly used pulse shaping filters to avoid ISI are Raised Cosine and Root Raised Cosine filters. Another source of bit errors in base band data transmission system is channel ...

Let's learn the equations and the filter model for simulating square root raised cosine (SRRC) pulse shaping.
i have been asked to show how a square wave is changed to raised cosine for pulse shaping. what i did was generated sequence of rectangular pulses and then passed it through firrcos filter. but teacher now said that i shouldnt be doing it this way i m supposed to gen...
