The flat top sampling is the one which can be represented in only a particular amplitude which cannot be changed with respect to the analog signal. this is true but let me add another difference that Is The ... WebJun 22, 2024 · Hence, from fig.1(b), it may be observed that by using flat top samples an amplitude distortion is introduced in the reconstructed signal x(t) from g(t). In fact, the high frequency roll-off of H(f) acts like a low-pass filter and thus attenuates the upper portion of message signal spectrum. These high frequencies of x(t) are affected.

WebAug 20, 2009 · Why flattop sampling is better than natural sampling in a Pam system? 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.In natural top scheme this is not possible. WebMay 25, 2024 · PAM, or pulse amplitude modulation, is the most basic form of pulse modulation, in which the signal is sampled at regular intervals and each sample is rendered proportional to the modulating signal’s amplitude at the sampling moment.
