SYNOPSIS
Dual-tone Multi-Frequency (DTMF) signaling is the basis for voice communications control and is widely used worldwide in modern telephony to dial numbers and configure switchboards. It is also used in systems such as in voice mail, electronic mail and telephone banking.
The detector part of early DTMF systems consisted of analog implemented bandpass filter banks, which were tuned to the eight standard frequencies. As analog lines as well as many other analog systems were converted to digital, researchers became ....etc

Low-Voltage Differential Signaling (LVDS) is a new technology addressing the needs of today's high performance data transmission applications. The LVDS standard is becoming the most popular differential data transmission standard in the industry. This is driven by two simple features: Gigabits @ milliwatts! LVDS delivers high data rates while consuming significantly less power than competing technologies. In addition, it brings many other benefits, which include:

a)Low-voltage power supply compatibility
b)Low noise generation
c)High no ....etc

for EE382C Embedded Software Systems
Abstract
Dual-tone Multi-frequency (DTMF) signals are used in touch-tone telephones as well as many other areas such as interactive control, telephone banking, and pager system. As analog telephone lines are converted to digital, researchers became interested in digital DTMF detectors.
There are many digital DTMF detecting algorithms, but most of them do not comply wit ....etc

INTRODUCTION
1.1 HISTORY OF WIRELESS COMMUNICATION
In the history of wireless technology, the demonstration of the theory of electromagnetic waves by Heinrich Rudolf Hertz in 1888 was important. The theory of electromagnetic waves was predicted from the research of James Clerk Maxwell and Michael Faraday. Hertz demonstrated that electromagnetic waves could be transmitted and caused to travel through space at straight lines and that they were able to be received by an experimental apparatus.

Low voltage differential signaling, or LVDS, is an electrical signaling system that can run at very high speeds over cheap, twisted-pair copper cables. It was introduced in 1994, and has since become very popular in computers, where it forms part of very high-speed networks and computer buses.
LVDS uses the difference in voltage between two wires to signal information. The transmitter injects a small current, nominally 3.5 milliamperes, into one wire or the other, depending on the logic level to be sent. The current passes through a resistor o ....etc
