When taking the DTFT of a discrete-time signal $x[n]=a \times u[n]$, the book "Signals and Systems" by Chi-Tsong Chen claims that the result is $\frac 1 {1-a \cdot e^{-j \cdot \omega \cdot T}}$; however, many other sources claim the DTFT is $\frac 1 {1-a \cdot e^{-j \cdot \omega}}$ without the T term.
