The sampling theory provides the necessary information to convert a continuous-time signal into a discrete-time signal and then into a digital signal with minimum error. The sampling process can be thought of as
Many empirical studies suggest that samples of continuous-time signals taken at locations randomly deviated from an equispaced grid (i.e., off-the-grid) ca
In many fields like sampling theory, signal processing, and inverse problems [29], the nodes x¯=xii=1m are deterministic and one needs to recover the function relation from values at these nodes. So the regularization scheme has the same form, but only {yi}i = 1m are (random) samples...
According to signal processing theory, we need to do three things to compute final values for each of the pixels in the output image: Reconstruct a continuous image function \tilde{L} from the set of image samples. Prefilter the function \tilde{L} to remove any frequencies past the Nyquist...

Sampling theory makes it possible to describe a DAC’s output signal in the time and frequency domains. Figure 3 shows the output signal for a DAC. Here, this is a sequence of rectangle pulses, the amplitude of which matches the corresponding digital value. Since the duration of these rectan...
1068Accesses Abstract Sampling theory has been studied in a variety of function spaces and our purpose here is to develop the theory in a Fourier algebra setting. This aspect is not as well-known as it might be, possibly because the approximate sampling theorem, central to our discussion, had...
3a, b). As predicted by network sampling theory, the psychometric distance between each pair of tasks showed a strong positive correlation with the corresponding whole-brain task activation DICE coefficients (r = 0.63, p < 0.001, Fig. 3c, d). This indicates that tasks that are ...
However, from sampling theory, it is known that intermediate data and hence the whole signal may be recovered from the sampled data if the sampling is done at a sufficiently fast rate. The sampling can be done directly at the RF frequency without the need to reduce it to IF, as we ...
