Exploring Electrical Conductivity in Metals: Deriving the Classical Theory
According to classical theory (described by drude ) generally free electrons move randomly in all possible directions and no net velocity results. If an electric field E is applied, the electrons are...
Negative Resistance: Breaking Down the Basics
What is resistance?
We know that electric current is nothing but only continuous flow of charges. The electric potential (voltage) difference established between the two terminals encourages...

Interview Questions: Microwave engineering (basic-3)
Microwave
Electromagnetic waves having frequencies between 1GHz to 300GHz (it may be 300MHz to 300GHz) are called microwaves.
Properties of Microwaves:
Microwave are unidirectional. This means...
Frequency Hopping Spread Spectrum: Fast vs slow
Frequency hopping spread spectrum (FHSS) is a method of transmitting radio signals by hopping or shifting carrier signals across numerous channels with pseudo-random sequence which is already known...
Active vs Passive Instruments: Understanding the Key Differences
When it comes to electronic instruments, there are two main types: active and passive. While both types are used to measure signals, they differ in the way they do so. In this article, we will explore...
Features of Intel 8086 microprocessor: A Beginner's Guide
Intel 8086 is a 16-bit microprocessor developed by Intel in the year between early 1976 and mid-1978 and released in 1978. It is an advanced version of the Intel 8080 microprocessor. The 8086 microprocessor...
Programmed I/O vs Interrupt-driven I/O: Understanding the Difference
Input/Output (I/O) operations are fundamental to computer systems. They allow the system to interact with external devices such as keyboards, mice, printers, and other peripherals. Two common methods...
Importance of I/O Module
What is I/O module?
The I/O (Input Output) module works as a mediator between I/O devices and the processor. It conveys the
information from I/O device (Sometimes called as peripheral or external...
Understanding Computer Interfaces: may be Hardware or Software
What is Interface ?
A computer interface is a concept that refers to a point of
interaction between objects or components and is applicable at the level of
both hardware and software. That is...
What do you mean by N-(such as 16) bit processor?
If you're new to processors, it's easy to understand that "a processor which can process n bits of data at a time is called an n-bit processor". But to understand it more accurately, we need to know...
