SMS through Telephone using AT89S8252
This system can transmit message or text through ordinary Land Line Telephone from one end (source) to another end (designation). The tecnology used is the DTMF(Dual Tone Multiple Frequency). technology. The system has two sections one for editing the text and to transmit the edited text and the other section consist for receiving the text message.There are several steps for this project:
* DTMF decoding/Encoding process
* Ring sensing
* ON/OFF hook detection
* Displaying the message in LCD

ppt for load scheduling load shedding

1.What is load shedding?

Load shedding is a measure of last resort to prevent the collapse of the power system country-wide. When there is insufficient power station capacity to supply the demand (load) from all the customers, the electricity system becomes unbalanced, which can cause it to trip out country-wide (a blackout), and which could take days to restore. When power is insufficient, Eskom can thus either increase supply or reduce demand to bring the system back into balance. As the difference betw ....etc

ABSTRACT
The objective of this project is to design an embedded system which can control appliances remotely. This project is designed to study the basic implementation of DTMF (Dual Tone Multi Frequency).
The DTMF signal is composed of high frequencies & low frequencies. Each key is assigned a low frequency and a high frequency. When a particular key is pressed, the frequencies those are specific to that particular key are transmitted. Therefore, no two keys will have a same set of low & high frequencies ....etc

implimentation of landline switching system using vhdl

A landline telephone (also known as land line, land-line, main line, home phone, landline, fixed-line, and wireline) refers to a phone that uses a metal wire or fibre optic telephone line for transmission as distinguished from a mobile cellular line, which uses radio waves for transmission. In 2003, the CIA reported approximately 1.263 billion main telephone lines worldwide. China had more than any other country at 350 million and the United States was second with 268 million. The United K ....etc
