Phase

Unit:SDL_fourier
Class:TFastFourier
Declaration:property Phase[ix: integer]: double;

The readonly array property Phase provides access to the phase spectrum (in radians). The index ix may assume values between 1 and SpectrumSize div 2. Accessing any value of the array below 1 and above SpectrumSize div 2 will result in a zero value on read. The first harmonic is stored in Phase[1], the second in Phase[2], and so on. Phase[0] does not make sense and always returns a zero value.

Example: This property is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): fft
