In PAM, the initial signal is sampled at the same intervals, as display in the figure. PAM is the infrastructure of an essential analog-to-digital conversion method known as pulse code modulation (PCM).
The sampling method used in PAM is more helpful to other manufacturing fields than data communication. This method creates an analog signal, samples it, and creates digital pulses sequences based on sampling. PAM represents pulse amplitude modulation. The first phase in analog to digital conversion is known as PAM. The various methods for Analog-to-Digital conversion are as follows − PAM In analog-to-digital conversion, the data involved in a constant waveform is modified into digital pulses.
It needed a decrease in the several values in an analog message defined in the digital flow. We require to digitalize the analog signal that is smaller inclined to noise. When an analog signal is digitalized, that is known as analog-to-digital conversion.Ĭonsider a human address a voice in the structure of an analog signal.
