The coefficient file for the single-rate FIR filter is straightforward and consists of a one-line header followed by the filter coefficient data. For example, the filter coefficient file for an 8-tap filter using a base-10 representation for the coefficient values is shown in This Figure :

X-Ref Target - Figure 3-38

Irrespective of the filter possessing positive or negative symmetry, the coefficient file should contain the complete set of coefficient values. The filter coefficient file for the non-symmetric impulse response shown in This Figure is presented in This Figure .
