Signal sampling theorem
WebAccording to the sampling theorem, for , the samples uniquely represent the sine wave of frequency .For , aliasing occurs, because the replicated spectra begin to overlap.In the range , a spectral line appears at the frequency .In the upper figure the sine wave with the corresponding frequency and color appears. Note that for and , additional lines at and … WebThe continuous signal S ( t) is represented with a green colored line while the discrete samples are indicated by the blue vertical lines. In signal processing, sampling is the …

WebHowever, when bandpass signals are to be sampled, lower sampling rates can sometimes be used. Failure to adhere to the sampling theorem for a bandlimited signal leads to a phenomenon known as aliasing.

WebMay 6, 2024 · The Nyquist sampling theorem, or more accurately the Nyquist-Shannon theorem, is a fundamental theoretical principle that governs the design of mixed-signal … WebThe sampling theorem is very important in signal processing. It tells us how fast we have to sample a signal with a given bandwidth to guarantee a unique correspondence between continuous- and discrete-time signals. This lesson “simplifies” the sampling theorem because it only uses the non uniqueness of discrete-time sinusoids and the ...
