Title: Implementing a lock - in amplifier using ATMEL microcontroller
Authors: Le Dinh Bach 
Keywords: Atmel microcontrollers;Lock;Amplifier
Issue Date: 2014
Publisher: Vietnamese-German University
Abstract: 
This project, firstly researches the problem of noise and signal, then implementing a digital Lock – in Amplifier with Atmel Microcontroller and use it to detect the signal from IR photo transistor. The goal of the project is to print out the parameters of the input signal (from IR LED). The project was done with the help of Arduino IDE, EAGLE and Filter Pro. Besides the basic principles of Lock –in Amplifier, Sallen Key topology and non – inverting amplifier should be studied for generate the reference signals and pre – process the input signal. The thesis work is divided into 3 parts: literature researching, software working and hardware working.
