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 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 …
