Introduction. In general, Steganography is a process of hiding confidential information in some another form. Then it can be stored in any form. Simplest example of that can be an envelop. Before sending any confidential files to someone, we envelop those file so others cannot view it. In this project we’ll store information in theContinue reading “LSB Image Steganography Software”

Sampling of Continuous Time Signal in MATLAB
The process of converting CT (continuous time) signal to discrete time signal is known as sampling. Sampling is very much necessary for digital systems because a computer cannot understand continuous time signals and sampling is the first step to convert any signal to its digital form. Simplest form of sampling:- Above figure shows the simplestContinue reading “Sampling of Continuous Time Signal in MATLAB”
Creating Signals in MATLAB
Signals are the physical quantity that varies with time. Some standard signals are very important to know behaviour of the system those signals are: Unit Impulse. Unit Step. Ramp. Sinusoidal. Sinc. Signum. In this blog we are going to create above mentioned signals creating anonymous function of each of them. These signals are also helpfulContinue reading “Creating Signals in MATLAB”
AC Current Measurement using Arduino Uno
In this project, we are using current transformer as current sensor. Current Transformer is a device/machine which converts high current from primary to low current at secondary winding which can be easily in proportion to transformation ratio. Current transformer has two windings primary and secondary, generally primary winding has single turn and secondary has largeContinue reading “AC Current Measurement using Arduino Uno”
Relay interfacing with Arduino
In this project we will interface relay to Arduino board. The relay is very useful element when it comes to operate switching A.C.(alternating current) or high power DC devices with micro controller. Relay are of many types and are available in wide range of actuating voltage i.e. 5V, 9V, 12V and so on. Though arduinoContinue reading “Relay interfacing with Arduino”
