Class AsymptoticRamp

java.lang.Object

com.jsyn.unitgen.UnitGenerator

com.jsyn.unitgen.UnitFilter

com.jsyn.unitgen.AsymptoticRamp

All Implemented Interfaces:

UnitSink, UnitSource

public class AsymptoticRamp
extends UnitFilter

Output approaches Input exponentially. This unit provides a slowly changing value that approaches its Input value exponentially. The equation is:

 Output = Output + Rate * (Input - Output);
 

Note that the output may never reach the value of the input. It approaches the input asymptotically. The Rate is calculated internally based on the value on the halfLife port. Rate is generally just slightly less than 1.0.
