Part of a Digital Signal Processing class

The goal of this project is to develop a DTMF synthesizer function using MATLAB software

Dual-tone multi-frequency (DTMF) generation and detection based on Goertzel algorithm

Decode the phone numbers from its voice with signal processing

DTMF decoder in Matlab implementing Goertzel's algorithm

A simple implementation of Dual Tone Multi-Frequency(DTMF) signalling encoder and decoder in python

My personal collection of useful Arduino sketches

DTMF - simple DTMF detector and visualizer using Matlab

This was my BTech degree Mini-Project during semester 5 and it is an electronic lock which can be unlocked from anywhere.

🚨 decoding and synthesizing DTMF signals. Processes a given signal and returns a list of decoded keys and the frequencies found in the signal and generates a DTMF signal from a given phone number.

In this project, range limitations of RF is eliminated using DTMF Technology

This is my Signal Processing lab that developed a Matlab model used to detect the dial tone and decode Dual Tone Multi Frequency (DTMF) signals.

A universal alarm platform based on esp8266 microcontroller.

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.

Midterm Performance Task in CPE416: Digital Signal Processing

A robot(car) that is controlled by the DTMF signals produced form a cellular phone.

Read DTMF key tones from an MP3/wav file in .NET

This Repository is for Basic 8051MicroControllers Operation and Interfaces with various devices like Bluetooth, DTMF, RFID, Timers, GSM, Serial Communication, Interrupts.

A web based DTMF encoder/decoder.
