Web1.1 Introduction. It is known [1], [3] that bandpass signals can be sampled with a sampling frequency which is lower than the sampling frequency according to the sampling theorem. Fig. 1 shows an example of how the spectrum of a bandpass signal sampled with f s f s (Fig. 1a) arises in the baseband with −f s/2 ≤ f < f s/2 − f s / 2 ≤ f ...
In signal processing, undersampling or bandpass sampling is a technique where one samples a bandpass-filtered signal at a sample rate below its Nyquist rate (twice the upper cutoff frequency), but is still able to reconstruct the signal. When one undersamples a bandpass signal, the samples are … See more The Fourier transforms of real-valued functions are symmetrical around the 0 Hz axis. After sampling, only a periodic summation of the Fourier transform (called discrete-time Fourier transform) is still available.
