Amplitude shift keying is a signal transform method when the carrying oscillation amplitude changes abruptly depending on the discrete data messages.
In frequency Modulation a carrier is more high-frequency comparing to the information signal and frequency-modulated signal amplitude is steady.
Frequency shift keying is a signal transform method when the carrying oscillation frequency changes abruptly depending on the discrete data messages.
Keying is the transition process of one or several high-frequency signal (which is called carrier) parameters under the law of low-frequency discrete data message.
The main modulation function is signal transformation or transfer from low-frequency range to higher for further transfer through radio or cable carrier line.
Phase Modulation is analog signal (carrier) transformation type when the signal changing parameter is its phase.
Phase shift keying is a signal transform method when the carrying oscillation phase changes abruptly depending on the discrete data messages.
Pulse Width Modulation (PWM) is signal duty changing (Duty is ratio pulse width to signal period).
As a rule Clipped Sine standard signal of arbitrary waveform generator is displayed in modern function generators or arbitrary waveform generators (AWG) (waveform generators).
