2. Root-Raised Cosine Formulas 2.1 Frequency Response Since the “root” aspect of a root-raised cosine filter is in the frequency domain, simply take the square root of the raised cosine frequency response given above to get the root-raised cosine frequency response. ...
1. Raised Cosine Filter Basics 1.1 What are Raised-Cosine (RC) Filters? (TBD) 1.2 Why are Raised-Cosine Filters used? (TBD) 1.4 What are Root-Raised-Cosine (RRC) filters? (TBD) 1.5 Why are both RC filters and RRC filters used?
receiver, a filter having the same percent raised cosine response but at a higher cutoff frequency which satisfies the formulawhere f is the cutoff frequency (6 db) of the new filter, f is one-half the baud rate of the modem, and 伪 is the percent raised cosine expressed in decimal ...
