hi can anbody tell me how to calculate the complex conjugate symmetric and anti-symmetric part of a signal?
ie., for example i have a signal \[x(t)\]. So how to find the complex conjugate symmetric and anti-symmetric part of it?

thnx

purna!

HI purnapragna,

a signal can be a complex signal as follows:x(t) = a(t) + ib(t) . in which the a(t) is the symmetric and the b(t) is the anti symmetric part.

The signal given by you is truly complex, but how would you justify that \[a(t)\] is symmetric and \[b(t)\] is anti-syymetric? By the by my question is that how do you find the conjugate-symmetric part and conjugate-anti-symmetric part of the given signal.

thnx

purna!

a complex signal x(t) is said to be conjugate symmetric if x*(t)=x(-t)

and conjugate symmetric part is =[x(t)+x*(-t)]/2
