Finite impulse response (FIR) decimation filter Since R2020b expand all in page Libraries: DSP HDL Toolbox / Filtering Description The FIR Decimator block implements a single-rate polyphase FIR decimation filter that is optimized for HDL code generation. The block provides a hardware-friendly inte...
The most important properties that make the FIR attractive (+) or unattractive () for selective applications include: FIR linear-phase performance is easily achieved. Multiband filters are possible. The Kaiser window method allows iterative-free design. FIRs have a simple structure for decimators ...

Digital signal processing (“DSP”) block circuitry on an integrated circuit (“IC”) is adapted for use (e.g., in multiple instances of the DSP block circuitry on the IC) for implementing finite-impulse-response (“FIR”) digital filters in systolic form. Each DSP block may include (1)...
A delay element 74 may be inserted to match the total delay in the low rate path comprising the decimator 68, low rate portion 66, delay 74, and interpolator 70 to the total delay through the set of delays 62A in the high-rate path. In an alternative arrangement the digital filter ...
A two-dimensional finite impulse response (FIR) filter comprises a demultiplexer for demultiplexing an input data signal comprising adjacent digital words into p (e.g. 2) slower data signals each havi
A decimator of the type having a decimation factor of K, is implemented by a finite impulse response (FIR) filter network of length N. The filter network includes N/K accumulators each of which arithmetically combines samples of an input signal as multiplied by a corresponding set of K ...
