Tutorial22: How to quantize coefficients that has very low cutoff
Many microprocessors don't have FPU(Floating Point Unit). In that case you need to quantize filter's coefficients. If you design an IIR filter that has very low cutoff frequency, please be careful of quantization. The coefficients should be finely quantized to have good characteristics.

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) to place parts.
