The process known as multirate digital signal processing increases the efficiency of digital filters and so enhances signal processing applications. The wide-ranging applications of this new technique include digital audio broadcasting (DAB), data transmission, and speech and audio sub-band coding. This study covers the fundamentals of filter design, sampling rate conversion, finite response filters, and filter banks and wavelets. It also shows how multirate signal processing can reduce the calculation rate required in digital filters
