When building systems for high-volume applications, it is very important to keep costs in check. There are several dimensions that affect total cost of ownership beyond the price per part. These...
IIR FILTER STRUCTURES BASED ON POLYPHASE DECOMPOSITION The efficient implementation of IIR decimation and interpolation filters can be achieved with polyphase structures. Developing a polyphase...
4. POLYPHASE FFT ECHO CANCELLATION In this section an example modification of the Subband adaptive polyphase FFT echo cancellation system [79] is presented in which the standard FIR filter banks are...
1. OVERVIEW OF POLYPHASE IIR FILTERS The idea of a polyphase structure can be easily derived from an FIR filter if all coefficients are substituted by appropriate allpass subfilters with constant...
The use of FPGAs in many applications is rapidly increasing. With the attributes of reconfigurability and design-to-working part times much faster than those of ASICs, FPGAs offer avionics engineers...
