Question: Obtain Hilbert transformation of cosine signal x(t)=cosθ by using MATLAB
Where θ=2πft
t is the time
f the frequency 0>f>0
Hilbert transformation can be obtained by equation bellow
H(x(t)) = 1/(π.t)*x(t)=x(f).j.sig(f)
Where * is time convolution
j, imaginary
x(f), Fourier transformation
sig(f), frequency sign
In other words, need to transform cosθ (whatever the frequency is) to sinθ by using MATLAB
