WebAug 19, 2024 · What is the difference between natural Pam and Flat Top Pam? In natural PAM, a signal sampled at Nyquist rate can be reconstructed, by passing it through an efficient Low Pass Filter (LPF) with exact cutoff frequency. Though the PAM signal is passed through a LPF, it cannot recover the signal without distortion. Hence, to avoid this noise, … 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. progressive of ozark bank

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. WebAug 27, 2024 · PAM is Pulse Amplitude Modulation. Now in practical life creation of an impulse signal is not easy. Instead a pulse train is supplied. There could be two types … WebApr 19, 2024 · Flat top PAM is a sampling technique.
