Detailed Description

Digital storage oscilloscope.

It shows what's going on in your signal(s). Adapts to the number of channels to show constellations or just eye diagrams. Requires a modulated signal with integer number of samples per symbol.

Learns most information from the signal - it is best to not pass parameters yourself.

While debugging, you can call the static method DSO_v1.plot(signal_interface object) or DSO_v1.plotSignal(y, Nss, Fs) to see how your signal looks.
