📞 Using Matlab to simulate Dual-Tone Multi-Frequency (DTMF) of telephone
A Java program to implement a DMTF Decoder.
An efficient way to implement FFT using Arduino
A real time frequency finder by reading the PCM input.
In this repository I store example scripts of some DSP algorithms made in MATLAB. These served an educational purpose when I wrote them, I'm making them public, since I had trouble finding example code.
calculate the coefficient k of Goertzel's algorithm
Using filtering techniques to smoothen hyper-sonic shockwave in MATLAB
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.
DTMF projects using DFT and Goertzel algorithm based implementations for Signal Processing class
Real-time DTMF tone decoder on ARM Cortex-M with LCD display, using Goertzel algorithm and modular embedded system design.
Add a description, image, and links to the goertzel topic page so that developers can more easily learn about it.
