The Sampling Theorem

WebA sine wave can be easily recognized by ear, as it sounds very pure, almost like a whistle. In 1822, French mathematician Joseph Fourier discovered that any waveform could be broken up as a combination of sine waves with different amplitude and frequencies. WebFirst, let's create a sine wave. The formula for this is: Fs = 1000; % Sampling frequency, e.g., Hz (samples/sec) T = 1/Fs; % Sampling period (time between samples, e.g., sec) L = 1000; % Length of signal (in samples) t = (0:L-1)*T; % Time vector % Sine wave parameters theta = 0; % Phase, in radians F = 10; % Frequency of sin wave (cycles/sec) recheck bloodworkWebNov 4, 2024 · it's found that the signal must be sampled at a sampling frequency greater than 2 f m; i.e. f s > 2 f m Note that even though the selection of f s = 2 f m would sufficiently work for most of the typical engineering signals, it … recheck bp sign

WebDigitizing the sine wave When we digitize a continuous signal like the sine wave, we take samples every 1/sr seconds, where sr is the sampling rate. The continuous time, t, is replaced by the digitzed n/sr where n is the sample number. We can thus use the formula sn= A × sin(2πfn/sr)
