This includes analog-to-digital conversion (ADC), digital-to-analog conversion (DAC), storage, and transmission. In effect, the system commonly referred to as digital is in fact a discrete-time, discrete-level analog of a previous electrical analog. While modern systems can be quite subtle in their methods, t… WebThe sampling theorem, which is also called as Nyquist theorem, delivers the theory of sufficient sample rate in terms of bandwidth for the class of functions that are bandlimited. For continuous-time signal x (t), which is band-limited in the frequency domain is represented as shown in the following figure. gite bourbon

Signal Sampling and Reconstruction - Johns Hopkins University

WebIn the sampling theorem we saw that a signal x (t) band limited to D Hz can be reconstructed from its samples. This reconstruction is accomplished by passing the sampled signal through an ideal low pass filter of bandwidth D Hz. WebThe process of sampling can be explained by the following mathematical expression: Sampled signaly(t) = x(t). δ(t)...... (1) The trigonometric Fourier series representation of δ …
