DTMF decoder in Matlab implementing Goertzel's algorithm

A simple frequency to number converter that I made for a CTF

DTMF - simple DTMF detector and visualizer using Matlab

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

Part of a Digital Signal Processing class

My personal collection of useful Arduino sketches

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

Decoder for DTMF (and other MF signals) in Python

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

Decode the phone numbers from its voice with signal processing

A hack initially for Moderskeppet Gaming geek cruise, I managed to drive a telephone off a 9V battery and pick up the keypad tones as input to act as an Amiga joystick, allowing the TV classic Hugo game to be played as in the good old days. Project diary and cleanup to come.

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

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.
