Digital and Analog is an integral part of Electronics. Most of the devices have both ADC as well as DAC and they are used when there is a need of converting signals either from analog to digital or digital to analog. Also the real world signals like sound and light are analog in the nature, so whenever …

This tutorial shows how to implement the Analogue to Digital Converter (ADC) function on ATMega32 using C code. It consists of code examples, and the meaning of some nomenclature such as sampling rate, and resolution. However before we get to the code, let us start from the beginning. The ATMega32 has a built-in 10-bit ADC. The input …
Introduction: We thought it would be interesting to try and construct a simple modem out of the ATMEL 8535. The main motivation for doing this was to test some DSP theories about the effects of transmission power, noise, and modulation technique on the bit error rate. Initially, we wanted to connect our modem to the …
Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volt, it understands zero volts (0V) as a binary 0 and five volts (5V) as a binary 1. But the real world is not so simple and likes to use shades …
