- FFTPHS(freqexpr)
-
- Returns the Fast Fourier Transform phase value corresponding to
- 'freqexpr' (-NYQUIST <= freqexpr <= NYQUIST) determined by the most
- recent invocation of the FFT procedure. FFTPHS is calculated as
- ARCTAN(FFTIM(freqexpr)/FFTRE(freqexpr)). Using FFTPHS in an expression
- does not automatically set the Y axis scaling values.
