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. Figure 5.7: Sampled signals illustrating the effect of adequate sampling and inadequate sampling process WebFeb 28, 2024 · Suppose we sample an 8 kHz sine wave at the commonly used rate of 48 kHz. The conditions of the sampling theorem are met since the sample rate is well above twice the maximum (and in this case only) frequency of the signal. Figure 1 shows one period of this sine wave with the sample points marked as red circles.

Sampling a continuous time signal produces a discrete time signal by selecting the values of the continuous time signal at evenly spaced points in … WebThe Nyquist-Shannon Sampling theorem is a fundamental one providing the condition on the sampling frequency of a band-width limited continuous-time signal in order to be able to reconstruct it perfectly from its discrete-time (sampled) version. It stated that the sampling frequency must be at least two times the highest frequency of the ...

WebThe answer is given by the Nyquist-Shannon sampling theorem, that may be simply stated as follows: The minimum sampling frequency of a signal that it will not distort its underlying information, should be double the frequency of its highest frequency component. If fS is the sampling frequency, then the critical frequency (or Nyquist limit) fN ... 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 ...
