B$.[5$ points$]$ The input signal to a Delta Modulation $($DM$)$ system is :

$m(t)=1\mathrm{.}25+5t$

The DM operates at a sampling frequency of $10$ Hz $,$ and has step size of $1$ volt. The first step at time zero.

Sketch the signal $m(t),$ and the $DM$ output $m_q(t)$ to scale for interval one second.

Determine the transmitted binary sequence.

Show whether overloading occurs or not.
