82.1 Discrete-Time Signals: Time-Domain Representation a complex sequence xn can be written as xn=xenl+jimiN) where and x. are the real and re imaginary parts of xn The complex conjugate sequence of xn is given by x*nxrela-jximIng Often the braces are ignored to denote a sequence if there is no ambiguity§2.1 Discrete-Time Signals: Time-Domain Representation • A complex sequence {x[n]} can be written as {x[n]}={xre[n]}+j{xim[n]} where xre and xim are the real and imaginary parts of x[n] • The complex conjugate sequence of {x[n]} is given by {x*[n]}={xre[n]} - j{xim [n]} • Often the braces are ignored to denote a sequence if there is no ambiguity
