WebThe Nyquist sampling theorem states that a band-limited analog signal can be perfectly reconstructed from the complete sequence of its samples if the sampling rate exceeds twice the highest frequency contained in the original signal. In our case, the sampling is done after down-converting them to IF. 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 WebA low pass signal contains frequencies from 1 Hz to some higher value. Statement of the sampling theorem. 1) A band limited signal of finite energy , which has no frequency components higher than W hertz , is completely described by specifying the values of the signal at instants of time separated by $\frac{1}{2W}$ seconds and. azフードショップ
