Correct Answer a) True, b) True
PAM (Pulse Amplitude Modulation):
The width and location of pulses in a modulated signal (PAM) are constant, while the amplitude of pulses varies proportionally with the amplitude of an analogical useful signal.

The pulses in a PAM signal may of Flat-top type or natural type or ideal type.
Generation of PAM:
There are two operations involved in the generation of PAM signal:
- Instantaneous sampling of the message signal m(t) every Ts seconds, where the sampling rate fs = 1/Ts is chosen in accordance with the sampling theorem. ('a' is True)
- Lengthening the duration of each sample so obtained to some constant value T. ('b' is True)
