The Higher the frequency of the sampling pulses lower the error in the demodulated PAM waveform is a false statement.
This is known to be a kind of modulation system where the signal is said to be sampled at regular intervals and all the sample is said to be made proportional to the amplitude of the signal at the time of sampling.
This method is one that transmits the data through the cat of encoding in the amplitude of a numbers of signal pulses.
