How do you make a sine wave in Matlab?

How do you make a sine wave in Matlab?

in sine function in MATLAB it is always sin(wt). here frequency w is in radian/sec not f (in HZ) so w will give you the no. of the cycle. if you want to use the sin(2*pi*60*t) you can use the sind(2*pi*9.545*t).

What is the equation of sine wave?

A general form of a sinusoidal wave is y(x,t)=Asin(kx−ωt+ϕ) y ( x , t ) = A sin ( kx − ω t + ϕ ) , where A is the amplitude of the wave, ω is the wave’s angular frequency, k is the wavenumber, and ϕ is the phase of the sine wave given in radians.

How do you write Sinx in Matlab?

Y = sin( X ) returns the sine of the elements of X . The sin function operates element-wise on arrays. The function accepts both real and complex inputs. For real values of X , sin(X) returns real values in the interval [-1, 1].

How do you write sin 2 in Matlab?

Direct link to this answer

1. x=0:0.01:2*pi;
2. si=sin(x).^2;
3. co=cos(x).^2;
4. plot(x,si,x,co);
5. figure;
6. plot(si,co);%not sure which one you want.

What does Syms do in Matlab?

The syms function creates a symbolic object that is automatically assigned to a MATLAB® variable with the same name. The sym function refers to a symbolic object that can be assigned to a MATLAB variable with the same name or a different name.

How do I run a MATLAB program in 2020?

On the Editor or Live Editor tab, in the Section section, select Run and Advance. Run the code in the selected section, and then run all the code after the selected section. On the Editor or Live Editor tab, in the Section section, select Run to End. Run to a specific line of code and pause.

How to generate a sine wave in MATLAB?

Sine Wave can be obtained by using the following formulae. x=sin (2*pi*fi*n) MATLAB Code: -. Sine wave:-. T=input (‘Input time of the Sinusoidal signal= ‘); fi=input (‘Input Frequency of the Sinusoidal signal= ); n =0:0.01:T; X=sin (2*pi*fi*n); stem (n,X);

Which is the correct frequency for the sine function in MATLAB?

in sine function in MATLAB it is always sin(wt). here frequency w is in radian/sec not f (in HZ) so w will give you the no.of the cycle. if you want to use the sin(2*pi*60*t) you can use the sind(2*pi*9.545*t). why i use the 9.545 bcz we should convert the f to w in the time interval of 2*pi.

What kind of software is used to plot sine waves?

Matlab is a software that processes everything in digital. In order to generate/plot a smooth sine wave, the sampling rate must be far higher than the prescribed minimum required sampling rate which is at least twice the frequency (f) – as per Nyquist Shannon Theorem.

What kind of function is a sine wave?

The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation. It occurs often in pure mathematics, as well as physics, signal processing, electrical engineering and many other fields.
