555 and 556 Timer Circuits
Introduction
The 8-pin 555 timer must be one of the most useful ICs ever made and it is used in many projects. With just a few external components it can be used to build many circuits, not all of them involve timing!
A popular version is the NE555 and this is suitable in most cases where a '555 timer' is specified. The 556 is a dual version of the 555 housed in a 14-pin package, the two timers (A and B) share the same power supply pins. The circuit diagrams on this page show a 555, ..............etc

The paper present the RF transmitter architecture based on All Digital Phase Locked
Loop (ADPLL) which is built from the ground up using digital techniques and digital
creation flow. In this paper, we described a system on chip that integrates ADSP with a multi Gega-Hertz digital RF transmitter that meets the blue tooth specifications.
A need has arisen to find digital architectural solutions to the RF functions. The frequency synthesizer is a key block used for frequency translation of radio signals and has been traditionally based on a ..............etc

Introduction
The Universal Asynchronous Receiver Transmitter (UART) is the most widely used serial data communication circuit ever. UARTs allow full duplex communication over serial communication links as RS232. UARTs are available as inexpensive standard products from many semiconductor suppliers, making it unlikely that this specific design is useful by itself.
The basic functions of a UART are a microprocessor interface, double buffering of transmitter data, frame generation, parity generation, parallel to serial conversion, double buf..............etc

Abstract
Mechine Health monitoring is of critical importance for safe and reliable machine operations. The design was based on the code division multiple access (CDMA) technique with the objective to provide a generic solution for embedded machine health monitoring systems .The design of a digital wireless data transmitter to extend the applicability of sensors to locations where wire based solutions are not feasible. This Topic Covers The Machine Monitoring based on embeded system..............etc

Laser Transmitter Plus Receiver
Transmitter is a laser tube connected to high voltage supply.The message to be transmitted is supplied to Audio in side with resistance of the coil 8ohm.The other side coil has resistance 2000ohm. When audio signal is given to the coil it modulates the high voltage supply and lazer tube will emit laser light in proportional to the sound signal .

FM Transmitter
The main components are microphone, antenna, 2N2222A NPN Transistor. The range of the transmitter when running at 9V is about 300 feet. Running it from 12V increases the range to about 400 feet. This transmitter should not be used as a room or telephone bug
