A Hall effect transducer is a sensor that detects a magnetic field and converts it into a proportional electrical signal using the Hall effect phenomenon. It is widely used for current sensing, position sensing, speed detection, proximity sensing, and magnetic field measurement in industrial, automotive, and consumer electronic systems. Unlike conventional mechanical or contact-based sensors, […]

TVS Diode: Symbol, Construction, Working, Types and Applications
A TVS (Transient Voltage Suppression) diode is a specialized semiconductor device used to protect electronic circuits from high-voltage transients such as electrostatic discharge (ESD), lightning surges, and switching spikes. It responds extremely fast and clamps overvoltage to a safe level before they damage sensitive components. Modern electronic systems are highly sensitive to voltage spikes caused […]
Surge Protector Circuit Diagram, Working, Types and Applications
A surge protector is an electronic protection device designed to safeguard electrical and electronic equipment from voltage surges (transient overvoltage). A voltage surge is a sudden and short-duration spike in voltage that exceeds the normal operating voltage of a system. These surges may last from a few nanoseconds to milliseconds but can reach several kilovolts […]
Difference Between Surge Protection and Over Voltage Protection
Understanding the difference between Surge Protection and Over Voltage Protection is essential for designing robust electronic systems, selecting the right protective components, and complying with safety and EMC standards. Modern electronic and electrical systems are increasingly sensitive to abnormal voltage conditions. With the widespread use of microcontrollers, SMPS power supplies, communication modules, and semiconductor devices, […]
BCD Subtractor Circuit Diagram, Truth Table, Working and Applications
While a BCD adder performs decimal addition using binary hardware with correction logic, a BCD subtractor performs the subtraction of one BCD number from another and produces a valid BCD result. This requires additional logic because simple binary subtraction does not automatically produce valid BCD outputs. Digital systems frequently need to perform arithmetic operations such […]
BCD Adder Circuit Diagram, Truth Table, Working and Applications
Let’s explore the BCD Adder Circuit and learn how it adds decimal digits using Binary Coded Decimal (BCD), a digital coding system in which each decimal digit is represented using a 4-bit binary number. BCD arithmetic is widely used in digital systems where calculations must remain in decimal form, such as calculators, clocks, and display-based […]
