How to generate a square wave with specif values

How to generate a square wave witch start from c0 and reaches c0+Vmax? Thanks for the support

N=1e5
Np=3
Fx=Np/N
n=(0:N-1)';
wt=2*pi*Fx*n;
c0=2
Vmax=5
phi1=pi/3

x_square=

Hi Edoardo,

To generate a square wave in MATLAB that starts at a baseline value c0 and reaches a maximum value of c0 + Vmax, you can check the following steps:

1. Define the necessary parameters required for generating the square wave and create a time vector.

N = 1e5;    
Np = 3;    
Fx = Np / N; 
n = (0:N-1)';  
wt = 2 * pi * Fx * n;  
c0 = 2;   
Vmax = 5;    
phi1 = pi/3;  

2. Calculate the angular frequency component and generate the square wave using the square function. Transform the wave to oscillate between c0 and c0 + Vmax.

% Generate square wave
x_square = c0 + (Vmax/2) * (1 + square(wt + phi1));

3. Plot the square wave to visualize it.

% Plot the square wave
plot(n, x_square);
xlabel('Sample Index');
ylabel('Amplitude');
title('Square Wave');
grid on;

Hope this solves your query!
