Tutorial26: How to implement FIR coefficients into dsPIC
DSP functions of "dsPIC" can make fine FIR filters which tap count exceeds 100. In this tutorial, I explain how to handle those coefficients.

The following figure is 127-tap FIR filter. We need to generate its coefficients and quantize them in order to implement the filter into a dsPIC. We use "DSPLinks" to do those tasks.

First of all, you need to download DSPLinks and install it on your PC.

Please start "DSPLinks" after installation.

A blank schematic appears.

Then please click "Parts" (Transistor icon) and click anywhere on the schematic. "Parts Select" dialog appears. Choose RMZLPF and click OK.
