3 Amplitude-Phase Spectrum
This function display the Amplitude-Phase Spectrum
of CH1 or CH2.
4 Real-Imaginary Spectrum
This function display the Real-Imaginary Spectrum
of CH1 or CH2.
4 Corrected Amplitude-Phase Spectrum
This function use improved FFT technique to estimate the spectrum peaks
and to reduce error of leakage and fence effect in FFT algorithm.
6 Transer Function
This function display the transer function of
CH1 or CH2. That CH1 is input signal and CH2 is output signal.
7 Coherent Function
This function display the coherent function of
CH1 or CH2. That CH1 is input signal and CH2 is output signal.
.
8 Power Cepstrum
This function display the power cepstrum signal
of CH1 or CH2.
.
Example.
a.Amplitude-Phase Spectrum of a square wave signal.
B.Transfer function of a low pass digital filter
designed by this program.
It is obtained by
produce a same white noise signal in CH1 and CH2, then filter signal of
CH2, and last do Transfer Function analyze.
