SignalProcessing.SinusoidSampleGenerator

java.lang.Object
- ptolemy.math.SignalProcessing.SinusoidSampleGenerator

All Implemented Interfaces:

DoubleUnaryOperation

Enclosing class:

SignalProcessing
```
public static class SignalProcessing.SinusoidSampleGenerator
extends java.lang.Object
implements DoubleUnaryOperation
```
This class generates samples of a sinusoidal wave. The function computed is :
```
  h(t) = cos(frequency * t + phase)
  
```
where the argument is taken to be in radians. To use this class to generate a sine wave, simply set the phase to -Math.PI*0.5 from the phase, since sin(t) = cos(t - PI/2).
