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.
To design a filter, identify coefficients that match the frequency response you specify for the system. These coefficients determine the response of the filter. You can change which signal frequencies pass through the filter by changing the coefficient values in the parameter editor.
