Sine wave in matlab

A sine wave or sinusoidal wave is a periodic function that involves the trigonometric sine function along with other factors such as Amplitude, frequency, and time instant of the wave.

Help Center Help Center. Generate sine wave physical signal, using simulation time as time source. The PS Sine Wave block outputs a sinusoidal waveform, while providing flexibility in how you specify the sine wave frequency. For more information, see Units for Angular Velocity and Frequency. The Frequency specification parameter lets you choose the method of specifying the frequency of the sine wave:.

Since T s is constant, the right-hand matrix is a constant and can be computed once at the start of the simulation.

If X is a matrix, then fft X treats the columns of X as vectors and returns the Fourier transform of each column. If X is a multidimensional array, then fft X treats the values along the first array dimension whose size does not equal 1 as vectors and returns the Fourier transform of each vector. If X is a vector and the length of X is less than n , then X is padded with trailing zeros to length n. If X is a vector and the length of X is greater than n , then X is truncated to length n.

Help Center Help Center. This example shows how to find the root mean square RMS value of a sine wave, a square wave, and a rectangular pulse train using rms. The waveforms in this example are discrete-time versions of their continuous-time counterparts. The length of the signal is 16 samples, which equals two periods of the sine wave. Create a periodic square wave with a period of 0. The square wave values oscillate between - 2 and 2. Create a rectangular pulse train sampled at 1 kHz with the following parameters: the pulse is on, or equal to 1, for 0. This means the pulse period is 0. This is referred to as the duty cycle.
