In digital signal processing, the frequency-domain analysis of discrete-time signal is an important phenomenon to perform. This process includes the conversion of time-domain sequence to an equivalent frequency-domain representation. The tools Discrete Fourier transform (DFT) and Discrete-time Fourier transform (DTFT) are used in this conversion. DFT is the better version of DTFT as problems that … Read more
Semiconductor materials can be categorized into two main classes: intrinsic semiconductors and extrinsic semiconductors. Intrinsic semiconductors are the pure form of semiconductor materials while extrinsic semiconductor materials are formed by adding some impurity to the pure semiconductors. The main difference between intrinsic and extrinsic semiconductor is that intrinsic semiconductors are pure in form, no form … Read more
The computer is the most widely used device throughout the world. It has become the second basic need of humans to carry out daily tasks. Now, we know that the computer is just another human brain. It contains memory where all the data and instructions are stored. Memory is a must and essential for every … Read more

We all have used computers at some point in our life. At times, we must have wondered how a computer accepts our language and gives command with an immediate output. But the fact is that the computer does not understand our textual language i.e. high-level language. A high-level language is understandable only by us i.e. … Read more
A screw can be defined in a broad category of mechanical fasteners which have a threaded shaft and are designed to screw into a part. They can have a tapered shaft with sharp threads which can cut a mating thread into which they are fastened. Unlike bolts, screws are self-tapping and have their entire part … Read more
In digital electronics, we classify circuits into two primary types which are – combinational circuits and sequential circuits. In the case of combinational circuits, the output depends only on the present input. Whereas, in the case of the sequential circuits, the output depends on the present input as well as the past output(s)/input(s). Due to … Read more
All the electronic components can be broadly classified into two main classes- Active components and passive components. Active components are those circuit elements that deliver energy or power to the circuit while passive components are the ones that utilize the power or energy in the circuit. Active components require an external source to operate while … Read more
We all are pretty aware that this era is a digital era. The 21st century is known for its out-of-the-box inventions and discoveries. This era has given us standards for living. There was a transition from 2G to 3G mobile networks generation. We have also seen 4G mobile technology coming into existence. It has completely … Read more
