SPECTRUM ANALYZER SCREEN

The spectrum analyzer tab is a very useful feature: It is a MPX and audio spectrum display.

Initially it shows the MPX from 0-65kHz so that the readings of the currently selected source

(composite MPX or stereo Left/Right) to be clearly visible. The signal source to be calculated

and visualized is chosen from the Source section placed on the right part of the screen. Spectral

components of the selected signal are determined on the base of Fast Fourier Transform.

The window function can be selected through the relevant menu with interactive buttons. The

available windows and their features are given below. This table can be used to choose the best

windowing function for each application.
