how can i seperate the value exp(1i*2*pi*bbbb);

3 views (last 30 days)
x1=exp(1i*2*pi*bbbb);
d1=bb1.*exp(1i*2*pi*bbbb);
d2=abs(d1);
d3=angle(d1);
d4=exp(1i*d3); %value are not same as x1
%how can i extract the value of x1 from d1

The question is unlcear.
Given d1 from [d1 = bb1 * exp(a)], are you asking how to get exp(a)? If so,
exp(a) = log(d1/bb1);

"i want to find the value of x1 from the d1"
x1 = d1/abs(d1)
if bbbb is real.
You need a major update of complex number theory.

d1=bb1.*exp(1i*2*pi*bbbb);
d12=abs(d1);
d13=angle(d1);
d16=d13./(2*pi);
here i m getting the change in phase at few elements ...value of d16 is same as bbbb but few values are going negative how to correct it
