WitrynaDrawing on the spectrum. Software Defined Radio software usually comes with a waterfall view ( spectrogram) that lets the user quickly inspect the spectrum. The spectrogram plots the amplitude of frequencies over time. This means, by carefully outputting a signal consisting of multiple frequencies, we can draw shapes and … WitrynaIt is recommended to display the spectrum with a linear scale, because the text scaling is frequency-linear based. You can activate the linear frequency scale in the Spectrogram Options dialog. Specify the Gain level. In the Processing section, open the Processing Algorithm menu and select Transcode Picture.
