SignalProcessing.Compute.Modify.Quantize
This node applies uniform amplitude quantization with a quantization step size $S$ that is selectable via the input slot step size.
The quantized signal $\mathrm{y}[n]$ is generated from the input signal $\mathrm{x}[n]$ with:
$\mathrm{y}[n] = S \cdot \mathrm{floor}( \frac{\mathrm{x}[n]}{S} + 0.5)$.
