📞 Using Matlab to simulate Dual-Tone Multi-Frequency (DTMF) of telephone

This work present homework number 2, part 1 from the subject Digital Signal Processing for the school year 2016/2017.

This repository contains all the Matlab codes that I have used to complete the DTMF Decoder and Encoder project in my winter semester. And I will also attach some screenshots and videos for better understanding.
