a time-continuous signal is defined as: x(t) = t^(2)/4 − t^(2); t ∈ [- t/2, t/2]; where t > 0 is some constant. (a) [5 pts.] sketch the graph of x(t). in matlab

To plot the graph of the time-continuous signal in MATLAB, you can use the following code:

main.m
% Define the time range t
t = linspace(-t/2, t/2, 1000); % You can adjust the number of points for a smoother curve

% Define the signal equation
x = (t.^2)/4 - t.^2;

% Plot the graph
plot(t, x);
xlabel('t');
ylabel('x(t)');
title('Graph of x(t)');
grid on;

13 lines

Make sure to replace t with the correct value or constant in the code. The code will create a line plot of the signal x(t) against the time t. Adjust the number of points in the linspace function to get a smoother curve if desired. The xlabel, ylabel, and title functions are used to label the graph. The grid on command adds a grid to the plot for better visibility.
