Sounds like homework ...
x = @(t) 20*t.^2.*(1-t).^4.*cos(12*pi*t);
t = linspace(0, 1);
figure(1)
plot(t, x(t))
grid

My pleasure.
That should be relatively straightforward with the Wavelet Toolbox.

You need it if you want to work with wavelets. (I don’t use it often enough to be comfortable dealing with Questions about it.) It’s very useful for denoising signals with broadband noise, and for isolating specific features from signals.

Perhaps.
Post it as a new Question.

hi. can you help me with this problem ?
sketch the continuous time signal
x(t) = u(t+1) - 2u(t-1) + u(t-3)
