Pulse-amplitude Modulation - Generation of PAM

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 word generation:

    We need to encourage members of this next generation to become all that they can become, not try to force them to become what we want them to become. . . . You and I can’t even begin to dream the dreams this next generation is going to dream, or answer the questions that will be put to them.
    Barbara Coloroso (20th century)
