Detailed Description

Signal processing functions.

Enumerations
enum class	FilterType { Lowpass , Highpass , Bandpass }
	Type of FIR filter.

Functions
TypedImage< float >	sinusoidReal (float samplingFrequency, float signalFrequency, int signalLength, float amplitude=1.0f, float phase=0.0f, int axis=0)
	Creates a 1D image with a sinusoid of the given frequency and length, phase = 0 means the signal is A*cos(f*2*pi*t).
TypedImage< float >	sinusoidComplex (float samplingFrequency, float signalFrequency, int signalLength, float amplitude=1.0f, float phase=0.0f, int axis=0)
	Creates a two-channel, 1D image with a complex sinusoid of the given frequency and length, A*exp(i*f*2*pi*t) = A*cos(f*2*pi*t) + A*i * sin(f*2*pi*t).
TypedImage< float >	createFirFilter (FilterType filterType, float samplingFrequency, float cutoffFrequencyLower, float cutoffFrequencyUpper, int filterLength, int axis=0)
	Creates a finite impulse response (FIR) filter, weighted with a hamming window, returned as a 1D image.
