Consider the sequence $x[n]=\left[\begin{array}{lll}-4- \uparrow{j} 5 & 1+j 2 & 4\end{array}\right]$
The conjugate anti-symmetric part of the sequence is
- $[-4-j 2.5 \quad j 2 \quad 4-j 2.5]$
- $[-j 2.5 \quad 1 \quad j 2.5]$
- $[-j 5 \quad j 2 \quad 0]$
- $\left[\begin{array}{lll}-4 & 1 & 4\end{array}\right]$
