WHAT IS PN SEQUENCE GENERATOR
Pseudo random Noise sequence generator is a circuit which generates pseudo random noise sequences.
A pseudo- noise sequence is a binary sequence with a noise like wave form that usually generated by means of a Linear feedback shift registers.

MATLAB stands for matrix laboratory. It is a technical computing environment for high performance numeric computation and visualization.MATLAB integrates numeric analysis, matrix computation, signal processing and graphics in an easy to use environment.
There are several toolboxes available from MATLAB. These tool boxes are collections of functions written for special application such as symbolic computation, image processing, statistics and control system design.
In Matrix laboratory there exist 3 major windows which is terme ....etc

MAT SWITCH

S.C. DWIVEDI


This simple circuit produces a warning beep when somebody crosses a protected area in your home or office. The switch, hidden below the floor mat, triggers the alarm when the person walks over it. The circuit uses a conductive foam as the switch. It can be two small pieces of conductive pads usually used to pack sensitive ICs as antistatic cover. Alternatively, you can make the switch by coating conducting carbon ink on two small pieces of a copper-clad board. When the circuit ....etc

use you can add and remove the survey programs you promote whenever you want.

Plus, when you promote your own website you are developing long-term traffic to it. Eventually you will make money every day even when you are not working.

These are several tips on making money referring new members to paid survey sites. This is a good way to increase your online income without spending time taking surveys every day yourself.

INTRODUCTION
Project Name: Mat Lab Based water marking

In this project our main aim to add a watermark in image. This project is useful for sites like SANTA BANTA.COM specially they have images to show on site, the user has to download images after viewing it on site, If there is no watermark than user will get image without paying to service provider, so to avoid this provider will add a watermark on their image and only than upload it for demo purposes. It is also helpful in some websites where some products images ....etc
