WebOBJECTIVE: The purpose of this lab is to study the relationship between discrete-time and continuous-time signals by examining sampling and aliasing. Computers equipped with sound cards can be used to explore some aspects of sampling and aliasing. In this lab, we will also generate signals and explore their effect as they are sampled and played back … WebThe discrete-time sinusoidal signal x [n]=5 cos(2p0.2n p 4). was obtained by sampling a continuous-time sinusoid of the form x (t)=A cos(2pft + f) at the sampling rate fs = 8000 …

WebAug 17, 2014 · The sampling theorem consists of two separate ideas: The first is aliasing, the concept that different continous time signals can result in the same discrete time signal. The second idea is reconstruction , that if the sampling rate is sufficiently high, the continuous signal can be reconstructed exactly (or at least with high accuracy) from ... WebReview Sampling Aliasing Aliased Frequency Aliased Phase Summary Example Aliased Frequency Let’s plug in ˚= 2ˇfn Fs, and 2ˇ= 2ˇFs Fs. That gives us: cos 2ˇfn F s = cos … WebDiscrete-time discrete-values signal •Continuous- valued signal take on all possible values on a finite or an infinite range. •Discrete-valued signals takes on values from a finite set of possible values. •A DT signal having a set of discrete values is called digital signal. 6 Ch 1- Introduction Eng.
