The first part of this series described how data flows through processing steps that create a moving average of stock prices over 65 days. Finite-impulse-response (FIR) filters use the same data-flow ...

As a parting shot, I pointed out that there are three quadratic terms there with unity coefficients of z 0 – and there are three deep nulls in the filter’s gain response, as was shown in the figures ...

Interpolation and Decimation Options Enable Better Performance and Lower-Power Filters to be Implemented in Altera PLDs Delivers Significant Performance and Cost Benefits over DSP Processors and ...

Part 2 shows how to optimize filter banks using high-level synthesis tools, and reviews the results of each optimization. Filter banks are part of a group of signal processing techniques that ...
