Altera

The FIR II FPGA IP core provides a fully-integrated finite impulse response (FIR) filter function optimized for use with Altera FPGA devices. The FIR II FPGA IP core has an interactive parameter editor that allows you to easily create custom FIR filters. The parameter editor outputs IP functional simulation model files for use with Verilog HDL and VHDL simulators. You can use the parameter editor to implement a variety of filter types, including single rate, decimation, interpolation, and fractional rate filters. Many digital systems use signal filtering to remove unwanted noise, to provide spectral shaping, or to perform signal detection or analysis. FIR filters and infinite impulse response (IIR) filters provide these functions. Typical filter applications include signal preconditioning, band selection, and low-pass filtering.
