Modifying transmit signal

In DSP-Proakis, I found the problem 2.56 interesting as it provides insight into delta modulation. The task is to show that,

$x(n) = \sum_{k=-\infty}^{\infty}[x(k)-x(k-1)]u(n-k)$

where
$x(n)$ is any discrete time signal and
$u(n)$ is the unit step function.

Quick check of $\LaTeX$ on Blogspot, thanks to the information provided here.

$\ exp^{\frac{j\pi}{4}}= \frac{1}{\sqrt{2}}+j\frac{1}{\sqrt{2}}$

Good ! It works…would like to have a better formatting though. Anyhow this will do for now.
