I am trying to sample a sine wave and plot it's frequency components, but I am having problems implementing it. 6991. The sine wave equation y = a * sin (2*pi*f*t + phi) computes the values of the sine wave at each time point in t, taking into account the frequency, amplitude, phase, and time vector. The dsp. The Sine Wave block generates a multichannel real or complex sinusoidal signal, with independent amplitude, frequency, and phase in each output channel. This MATLAB exercise will demonstrate this relationship. The difference equation to generate sin (w 0 n) u (n) is y [n] = sin (w 0) x [n-1] + 2 cos (w 0) y [n-1] - y [n-2] and the input signal x [n] is the discrete-time impulse. 4. Sep 23, 2025 · What goes wrong: by multiplying time vector t by 2*pi*60 your discrete step size becomes 0. How to generate Continuous and Discrete sine waves in MATLAB? | Basics of MATLAB programming In this video I have discussed about some basic MATLAB programs and I have done line by line This MATLAB exercise will demonstrate this relationship. Dec 4, 2021 · 1. For example, if you have a CSV file named `data. To plot a given signal on graph paper by using different values of the time. For a sine wave with desired frequency f 0 = 1 kHz and a sampling rate of f s = 16 kHz, determine the appropriate discrete-time frequency ω 0 in radians per sample. fMATLAB Program Expected Outcome The rectangular pulse and sine wave are successfully generated in discrete time. Finally, the plot () function is used to plot the sine wave, and labels and a title are added to the plot for clarity. fResult The Sine Wave block generates a multichannel real or complex sinusoidal signal, with independent amplitude, frequency, and phase in each output channel. % Program to generate Sine wave signal of given amplitude, frequency and phase change This MATLAB function computes the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm. Importing Data into MATLAB If your data resides in external files like CSV or Excel spreadsheets, MATLAB provides straightforward methods to import these datasets.
