<p>I was looking at degree audit and for EEL 3135 it says the following</p>
<p>EEL 3135
Introduction to Signals and Systems
Credits: 3; Prereq: CGS 2425, CIS 3020 and MAC 2313; Coreq: MAP 2302, and one of EEL 3105, MAS 3114 or MAS 4105. </p>
<p>is it required to take BOTH CGS2425 and CIS 3020? or is this a mixup, they are both programming classes.
and i think CGS245 might have been phased out, i think</p>
