Constructor Detail

SignalProcessing.SawtoothSampleGenerator

public SignalProcessing.SawtoothSampleGenerator(double period,
                                                double phase)

Construct a SawtoothSampleGenerator with the given period and phase. The phase is given as a fraction of a cycle, typically ranging from 0.0 to 1.0. If the phase is 0.0 or 1.0, the wave begins at zero with a rising slope. If it is 0.5, it begins at the falling edge with value -1.0. If it is 0.25, it begins at +0.5.

Method Detail

operate

public final double operate(double time)

Return a sample of the sawtooth wave, sampled at the specified time.

Specified by:

operate in interface DoubleUnaryOperation

Parameters:

time - The operand.

Returns:

The results of the operation.
