|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.
