How to create and plot square wave on specified "Tau" value

Message funciton of m(t) is basically two square wave. My question is how can i create one these square waves ?

(From duality property left square wave's formula become this =>2*sinc((t-1)*2) and then i can plot this equations graph, maybe ?)

% Define the time vector from -10 to 10 with 1000 points
t = linspace(-10, 10, 1000);

% Define the square wave function
square_wave = @(t, center) double(abs(mod(t - center, 2)) < 1);

% Create the square waves with different centers
wave1 = square_wave(t, 1);
wave2 = square_wave(t, 3);

% Calculate the message function m(t) as the difference of the two square waves
m_t = wave1 - wave2;

% Plot the square waves and the message function m(t)
figure;
hold on;
plot(t, wave1, 'DisplayName', 'Square Wave 1 (centered at t=1)');
plot(t, -wave2, 'DisplayName', 'Square Wave 2 (centered at t=3)'); % Negative for subtraction
plot(t, m_t, 'DisplayName', 'Message Function m(t)');
hold off;

% Add title and axis labels
title('Square Waves and Message Function m(t)');
xlabel('Time t');
ylabel('Amplitude');

% Add grid and legend
grid on;
legend show;

Uses an anonymous function to define the square wave, then calculates the waveforms and the message function. Finally, it plots all the functions on the same graph, with a legend to distinguish them.
