The low-frequency signal that is capacitively coupled to the 555 timer in PWM communications is called the modulating signal. The carrier is the high-frequency signal that is being modulated, the pulse-width signal is the resulting signal from the modulation process, and FM stands for frequency modulation, which is a different type of modulation.
