How to plot continuous time signals in Matlab?
This should get you started:
1u = @(t) t>=0;2x = @(t,u) cos(200*pi*t.*u(t));3t = linspace(-1, 1);4figure(1)5plot(t, x(t,u))6grid.How do you find the continuous time in Fourier transform?
The Fourier analysis evaluates signals and systems in the frequency domain.
Continuous time Fourier transform of x(t) is defined as X ( ω ) = ∫ − ∞ + ∞ x ( t ) e − j ω t d t and discrete time Fourier transform of x(n) is defined as X(ω)=Σ∀nx(n)e−ωn.
