The Half Adder & Full Adder
The Half Adder
Adds two binary digits
Produces a sum bit(S) and a carry bit(C)
Carry C is the AND of A and B
ie,C=AB
Sum is the X-OR of A and B
ie,S=AB+AB
The Full Adder
Adds two bits and a carry input
Outputs a sum bit and a carry
Adds the bit A&B and carry frm previous column(carry in)

Abstract
This paper proposes a feed-forward control in a halfbridgeresonant dc page link inverter. The configuration of feed-forwardcontrol is based on synchronous sigma-delta modulation and the halfbridgeresonant dc page link inverter consists of two inductors, onecapacitor and two power switches. The simulation results show theproposed technique can reject non-ideal dc bus improving the totalharmonic distortion.
Keywords—Feed-forward control, Resonant dc page link inverter,Synchronous sigma-delta modulation.

FADEC is the acronym for Full Authority Digital Engine Control. It is a system consisting of a digital computer (called EEC /Electronic Engine Control/ or ECU /Electronic Control Unit/) and its related accessories which control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines, their primary difference due to the different ways of controlling the engines.

Electronics' superior accuracy led to early generation analogue electronic control first used in Concorde's Rolls-Royce Olympus 5 ....etc

Single-phase half-bridge inverter


Operational Details

Consists of 2 choppers, 3-wire DC source
Transistors switched on and off alternately
Need to isolate the gate signal for Q1 (upper device)
Each provides opposite polarity of Vs/2 across the load

DC Supply Current
If the inverter is lossless, average power absorbed by the load equals the average power supplied by the dc source.
For an inductive load, the current is approximately sinusoidal and the fundamental component of the o ....etc

1. INTRODUCTION

Computer chips of today are synchronous. They contain a main clock, which controls the timing of the entire chips. There are problems, however, involved with these clocked designs that are common today.

One problem is speed. A chip can only work as fast as its slowest component. Therefore, if one part of the chip is especially slow, the other parts of the chip are forced to sit idle. This wasted computed time is obviously detrimental to the speed of the chip.

INTRODUCTION
Efficient control of D.C motor speed is very economical to any industries for that reason we are using full wave rectifier in which we are using triacs as switches because of bi-directional nature of triacs we are preferred instead of using thyrister as a switches. To obtain a four quadrant operation we need 8 switches if we use thyristers (this circuit called dual converter) and if we use triacs we need 4 switches only.

Pick up any newspaper today and it is a safe bet that you will find an article somewhere relating to mobile communications. If it is not in the technology section it will almost certainly be in the business section and relate to the increasing share prices of operators or equipment manufacturers, or acquisitions and take-overs thereof. Such is the pervasiveness of mobile communications that it is affecting virtually everyoneâ„¢s life and has become a major political topic and a significant contributor t ....etc
