Among the types of modulation techniques, the main classification is continuouswave modulation and pulse modulation. A continuouswave goes on continuously without any intervals and it is the baseband message signal, which contains the information.

Amplitude modulation a1 49 you will see in this experiment, and in others to follow, that there is no problem in generating an am signal with a depth of modulation exceeding 100%, and without any rf distortion whatsoever. Cest une modulation damplitude comportant une seule raie spectrale.
The idea is simple, though the notion that it can be used to modulate signals for transmission was hardly obvious before its discovery. Sti2dmodulation page 16 modulation, demodulation dun signal.
