 ## Signals and Systems  ### APP DESCRIPTION:

```The app is a complete free handbook of Signals and Systems with diagrams and graphs. It is part of electrical and Communications engineering education which brings important topics, notes, news & blog on the subject. The App serves as a quick reference guide of electrical and Communications engineering subject.

It covers 131 topics of Signals and Systems in detail. These 131 topics are divided into 5 units.

The App covers the topic in a flashcard-like format, the purpose of the App is faster learning and revisions of the subject. You can consider this App as notes which professors guides with in a classroom.

You can very easily pass and succeed in your exams or interviews, if you have this App on your mobile phone, and give an overview just a day.
