The FIR Filter block lets you design any FIR filter desired.Frequency response can be shaped by specifying the appropriate coefficients.
This block has numeric textbox to edit the tap size for number of coefficients to be used for FIR Filter calcualtion. Click on 'table' button to open the table editor window to enter the calculated coefficients as per desired filter requirement.
