Fundamentals of Information Systems


INPUT DEVICES

Input devices gather and translate data into a form the computer understands.
Primary input device:
Keyboard - Most common input device; used to type in commands and data.
Mouse - Enhances user’s ability to input commands, manipulate text, images.
Scanners are peripheral input devices which allow users to import:
Text
Graphics
Images

Space-Time Adaptive Processing: Fundamentals


ABSTRACT


Space-time Adaptive Processing (STAP) is a signal processing technique most commonly used in radar systems. It involves adaptive array processing algorithms to aid in target detection. Radar signal processing benefits from STAP in areas where interference is a problem (i.e. ground clutter, jamming, etc.). Through careful application of STAP, it is possible to achieve order-of-magnitude sensitivity improvements in target detection.STAP involves a twodimensional filtering technique ....etc

Introduction
Due to it’s relative simplicity and low hardware overhead (as compared to parallel interfacing), serial communications is used extensively within the electronics industry. Today, the most popular serial communications standard in use is certainly the EIA/TIA–232–E specification. This standard, which has been developed by the Electronic Industry Association and the Telecommunications Industry Association (EIA/TIA), is more popularly referred to simply as “RS–232” where “RS” stands for “recommended standa ....etc

Fundamentals of Power Electronics
1.1 Introduction to Power Processing
Control is invariably required
High efficiency is essential
High efficiency leads to low power loss within converter
Small size and reliable operation is then feasible
Efficiency is a good measure of converter performance
A high-efficiency converter
A goal of current converter technology is to construct converters of small size and weight, which process substantial power at high efficiency
Devices available to the circuit designer
Power loss in an ideal swi ....etc

COLOUR FUNDAMENTALS AND COLOUR MODELING


INTRODUCTION
 Color is a powerful descriptor that simplifies object identification and extraction from a scene.
 Characterization of light is central to the science of color.
 Achromatic light is what viewers see on a black and white TV.
 Gray-level is a scalar measure of intensity that ranges from black, to grays, and finally to white.
