In the current digital era, images have become one of the key channels for communication and information. There are multiple platforms where digital images are used as an essential identity, like social media platforms, chat applications, electronic and print media, medical science, forensics and cr...
Digital Signal Processing - Signals-DefinitionDefinitionAnything that carries information can be called as signal. It can also be defined as a physical quantity that varies with time, temperature, pressure or with any independent variables such as speech signal or video signal....
Digital Signal Processing - Static Systems - Some systems have feedback and some do not. Those, which do not have feedback systems, their output depends only upon the present values of the input. Past value of the data is not present at that time. These
The signal is un-altered as the pulse needs a high disturbance to alter its properties, which is very difficult. Signal processing functions such as encryption and compression are employed in digital circuits to maintain the secrecy of the information. The probability of error occurrence is reduced...
Digital Signal Processing - Basic DT Signals - We have seen that how the basic signals can be represented in Continuous time domain. Let us see how the basic signals can be represented in Discrete Time Domain.
Digital Signal Processing - Linear Systems - A linear system follows the laws of superposition. This law is necessary and sufficient condition to prove the linearity of the system. Apart from this, the system is a combination of two types of laws ?
Digital Signal Processing - Basic CT Signals - To test a system, generally, standard or basic signals are used. These signals are the basic building blocks for many complex signals. Hence, they play a very important role in the study of signals and syste
Digital Image Processing - Image Transformations - Before we discuss, what is image transformation, we will discuss what a transformation is.
