Abstract:
A signal processing apparatus has a first memory in which plural pieces of FIR coefficient data used for implementing an FIR filter algorithm are stored, a second memory which stores plural pieces of input data to be subjected to the FIR filter algorithm, and a processor implements the FIR filter algorithm using the plural pieces of FIR coefficient data stored in the first memory and the plural pieces of input data stored in the second memory as many times as the number corresponding to a designated filter order, in which filter algorithm each piece of coefficient data and each piece of input data are multiplied together and resultant products are summed up. The signal processing apparatus is provided, which can implement plural sorts of FIR filter algorithms of filter order which can be changed flexibly.

Claim (Index 4):
The signal processing apparatus according to  claim 1 , further comprising:\n a filter algorithm implementing unit which implements a first-order filter algorithm, wherein the first memory stores plural coefficient data sets as many as the number corresponding to the filter order of the filter algorithm at least for one sort of filter algorithm of variable filter order; the second memory stores input data set from the last sample to the sample before the (filter order\u22121)-th sample for the filter algorithm as delay data set; and the processor successively supplies the coefficient data stored in the first memory and current input data or the delay data stored in the second memory to the filter algorithm implementing unit for each filter algorithm, and makes the filter algorithm implementing unit repeatedly implement the first-order filter algorithm by time division processing of a dividing time length corresponding to the filter order and output output-data within each sampling period.
