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

Abstract-


Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipat ....etc

Mobile ad hoc networks (MANETs) are infrastructure-less and can be set up anywhere, anytime. They can host a wide range of applications in rescue operations, military, private, and commercial settings. Multimedia conferencing is the basis of a wealth of killer applications that can be deployed in MANETs. Some examples are audio/video conferencing, multiplayer games, and online public debating. Signaling is the nerve center of multimedia conferences”it establishes, modifies, and tears down conferences. This paper focuses on signaling for ....etc

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
