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 […]
Diode Clamper Circuit Diagram, Types, Working and Applications
This article explains clamper circuits from the ground up including their types, mathematical analysis, waveforms, working principle, differences, applications, and real-world design considerations. Clamper circuits are fundamental waveform-shaping networks used in electronics to shift the entire signal level either upward or downward without altering the overall shape of the waveform. Unlike clippers, which remove or […]
Diode Clipper Circuit Diagram, Types, Working and Applications
A Clipper Circuit, also called a limiter, is an electronic circuit that removes or “clips” selected portions of an input signal without distorting the remaining waveform. Its primary purpose is to prevent a signal from rising above or falling below a specified voltage level. Because of this, clippers are widely used in waveform shaping, signal […]
Energy Band Theory of Solids: Conductors, Semiconductors, and Insulators
Energy band theory of solids explains why some solids conduct electricity easily, why some do not, and why others behave in-between. Classical physics could not explain electrical conduction fully, but quantum mechanics and band theory together provide a complete picture. Solids are materials in which atoms are closely packed in a regular or irregular arrangement. […]
Voltage Multiplier Circuit Diagram, Working, Types and Applications
Voltage multiplier circuit forms a fundamental building block in high-voltage power supplies where the output voltage must be several times greater than the peak input voltage, yet the load current required is relatively small. Instead of using high-turn-ratio transformers which are large, expensive, and limited by insulation and core saturation constraints engineers often implement multipliers […]
