Sampling and Reconstruction of analog signal - File Exchange

WebIn signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values. WebIdeal Reconstruction • The sampling theorem suggests that a process exists for reconstructing a continuous-time signal from its samples. • If we know the sampling rate and know its spectrum then we can reconstruct the continuous-time signal by scaling the principal alias of the discrete-time signal to the frequency of the continuous signal. lobo chained
