public class QuantizedSampler extends Transformer
This quantizer is designed to take an input signal and send it to its output port if the signal has changed by more than a quantum relative to the last signal seen at the input port.
The number of outputs produced by this actor is dependent on the input values, so it should not be used with domains like SDF.

void |
attributeChanged(Attribute attribute)
If the argument is the quantum parameter, then cache
the value.
|
void |
fire()
Produce an output equal to the input if the input has crossed
the quantum; otherwise, produce no output.
