The transfer function represents the relation between an input signal and output signal in the frequency domain, allowing the determination of amplitude and phase.
In this mathematical calculation category, the RIONOTE supports coherence function and cross spectrum processing.
After completing waveform recording (as explained above), the stored waveforms can be displayed on the Main Control Unit's large screen, and played back by using the earphone jack output. Moreover, various secondary post processing functions for the waveform data are available in the Main Control Unit, including FFT analysis as shown in the screen example below.
