Generation of PAM
The signal is sampled at regular intervals and each sample is made proportional to the magnitude of the signal at the instant of sampling. These sampled pulses may then be sent either directly by a channel to the receiving end or may be made to modulated using a carrier wave before transmission.
For the generation of a PAM signal we use a flat top type PAM scheme because during the transmission,the noise is interfered at top of the transmission pulse which can be easily removed if the PAM pulse in flat top.

Famous quotes containing the words generation of and/or generation:
“Man is distinguished, not only by his reason; but also by this singular passion from other animals ... which is a lust of the mind, that by a perseverance of delight in the continual and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.”
—Thomas Hobbes (1588–1679)
“But it is fit that the Past should be dark; though the darkness is not so much a quality of the past as of tradition. It is not a distance of time, but a distance of relation, which makes thus dusky its memorials. What is near to the heart of this generation is fair and bright still. Greece lies outspread fair and sunshiny in floods of light, for there is the sun and daylight in her literature and art. Homer does not allow us to forget that the sun shone,—nor Phidias, nor the Parthenon.”
—Henry David Thoreau (1817–1862)
