Hi @Mvana

Cannot open your jpg (I'm lazy to fix the link). If you study Pure Math in high school, you need to use the sign function to clip the signal. But in MATLAB, it's a pretty easy job do something like this. In Electrical Engineering, you can use the Diode Clipper circuit.

% original sine wave
t = linspace(0, 6*pi, 3600*3+1);
x = 7*sin(t);
plot(t, x, 'linewidth', 1.5), hold on

% clipped sine wave
ub = 4;     % upper bound 
lb = -4;    % lower bound
y = max(lb, min(x, ub));
plot(t, y, 'linewidth', 1.5), hold off

grid on, xlabel('t'), ylabel('x(t)'), ylim([-10 10])

@Sam Chak, i followed the instruction the exact same way as you instructed @Mvana but im only getting 1/3, is there another way to get all 3 correct

[Sam Chak]

@Thando, Not exactly sure what you meant by getting 1/3 and all correct. Please enlighten.

how do i use the end function? i have a row by column vector and matlab instructions say that i must use the end command,but it gives me an error when i try it. What can i do to solve this problem?
