Binary to Decimal and Decimal to Binary Conversion
The number system that we are mostly familiar with is a decimal number system. The decimal number system has a base of ten which implies that there are ten numbers by the help of which we can represent any number of the decimal family. The numbers are from 0 to 9. Representation is such as…

Binary Number System
What is the Binary Number System? In digital electronics Binary numbers are the most important tool for giving digital inputs. Now before understanding binary number system, we have to understand decimal number system, which we use in our daily life. The number system first introduced in human history for counting purpose. Different numbers for counting…

Binary to Octal and Octal Binary Conversion
We know that binary and octal are two different kinds of number systems whose bases are 2 and 8 respectively, i.e. they use 2 and 8 digits respectively to represent their numbers and these numbers are 0, 1 (for binary) and 0, 1, 2, 3, 4, 5, 6, 7 (for octal). Now we can transform…

Octal Number System
In early days octal number system was mostly used in minicomputers. The word “OCT” means eight. The octal number system says that it is a number system of base 8 which means that we require 8 different symbols in order to represent any number in octal system. The symbols are 0, 1, 2, 3, 4,…

Digital Electronics: Basics and Definition
What is Digital Electronics? We know there are two types of signals, one is analog or continuous signal and the second one is Digital or discrete signal. So the science or field of research in the area of engineering is termed as Analog and Digital Electronics respectively. Now coming to the area of Digital Electronics,…

Arduino vs Raspberry Pi
What is an Arduino? Arduino is an open-source hardware development board. It has a programmable circuit board and a software (IDE- Integrated Development Environment) that runs on Mac, Windows, and Linux. Arduino was developed at the Ivrea Interaction Design Institute by Massimo Benzi in Italy. It was developed for fast prototyping, and aimed at people…

Thyristor Protection
Protection of a device is an important aspect for its reliable and efficient operation. Silicon Controlled Rectifier (SCR) are a very delicate semiconductor device. So we have to use it in its specified ratings to get desired output. SCR may face different types of threats during its operation due to over voltages, over currents etc.…

Rating of SCR or Thyristor
Thyristor ratings or SCR (Silicon Controlled Rectifier) ratings are very much required for operating it in a safe zone. The reliable operation can be done when a thyristor does not violate its voltage and current rating during working period. A thyristor, or SCR may have several ratings, such as voltage, current, power,,, turn on time,…

Switching or ON OFF Characteristics of SCR
Turn ON Time of SCR A forward biased thyristor can be turned on by applying a positive voltage between gate and cathode terminal. But it takes some transition time to go from forward blocking mode to forward conduction mode. This transition time is called turn on time of SCR and it can be subdivided into…

Two Transistor Model of SCR or Thyristor
Basic operating principle of SCR, can easily be understood by the two transistor model of SCR, as it is a combination of p and n layers. This is a pnpn thyristor. If we bisect it through the dotted line then we will get two transistors i.e. one pnp transistor with J1 and J2 junctions and…
