Sampling of sine wave
WebThe code has been updated such that when the switch is pushed, the red LED of the RGB LED illuminates and a 666.66 Hz cosine is created for around 5 seconds. The gain is set to 5 and the sample frequency is set to 8 kHz. The sine table array is changed to include 16 values, each of which is the matching sine wave value at a frequency of 666.66 Hz.

Websine = dsp.SineWave creates a sine wave object that generates a real-valued sinusoid with an amplitude of 1, a frequency of 100 Hz, and a phase offset of 0. By default, the sine wave object generates only one sample. sine = dsp.SineWave (Name,Value) creates a sine wave object with each specified property set to the specified value. 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)
Webfunction x = ssin (f0,Fs,N) % f0 = sine wave frequency [Hz] % Fs = sampling frequency [Hz] % N = number of samples dt = 1/Fs; % Sampling period [s] T = N*dt; % Record window duration [s] t = 0:dt: (T-dt); % Time vector for sampling [s] % generate samples at the specified times x = sin (2*pi*f0*t); % [signal units] stem (t,x) end % run the … A sine wave, sinusoidal wave, or just sinusoid is a mathematical curve defined in terms of the sine trigonometric function, of which it is the graph. It is a type of continuous wave and also a smooth periodic function. It occurs often in mathematics, as well as in physics, engineering, signal processing and many other fields.

WebJun 16, 2024 · If you want a pretty sine wave, you need to sample way more than twice the frequency, and everyone defines "pretty" differently, so there's no fixed number. I usually use 100 points per cycle of a sine wave -- but that would get pretty time intensive given that you want to plot three seconds of a 1.7MHz sine wave. Share Improve this answer Follow
