Sampling

Consider the continuous-time signal x(t), and a train of impulses where Ts,  is the sampling interval, and fs, is the sampling frequency. Multiplying ...

A continuous-time signal is sampled using impulse-train sampling followed by the zero-order hold method. Impulse-train sampling uses a periodic impulse ...

Consider a continuous signal and its sampled counterpart with a sampling period T. Applying a zero-order hold to the sampled signal results in a piecewise ...

Consider a time-domain signal and its Fourier transform to reveal the spectrum. Sampling the signal at a specific frequency creates multiple scaled ...

Consider a sampled sequence with zero values between sampling instants. Replace it by taking every N-th value of the sampled sequence. The original and ...

Consider a decimated signal with a reduced frequency range due to its lower sampling rate. Insert zeros between each sample to upsample, that introduces ...

Consider a signal sampled at a rate greater than twice its highest frequency. A signal with most of its energy concentrated in a narrow frequency band is ...
