Homework Statement
Hi,
I would like to get feedback if my z-plot is accurate for the following complex exponentiala:
Code:
a=2*exp(j*∏*t)
b=2*exp(j*∏*-1.25)
c=1*exp(j*∏*t)
d=-j*exp(j*∏*t)
Further analysis:
a= -2 because cos(∏) = -1 and sin(∏)=0
b= actual complex number A*cos(∅)+j*sin(∅)
c= -1 because cos(∏) = -1 and sin(∏)=0
d=+j because -j*cos(∏)= +j and -j*j*sin(∏)=0
However according to solutions from other source my analysis is wrong.
I've decided to plot both graphs in MatLab so you can see the difference:
(my solution on the left)/(solution from other source on the right)
2.
A*exp(x)=A*cos(x)+A*j*sin(x)
3.
As stated in one, theory doesn't agree with solution found on the internet.
Also, in whatever form I put the exponential in the function I keep getting totally different results.
e.g.
[2*exp(j*pi), 2*exp(j*pi*-1.25), 1*exp(j*pi), -j*exp(j*pi)] would not give me similar amplitude as above for some reason.
P.S. Ignore the R{1} on the left graph.
