4 bit Arithmetic and Logic Unit (ALU ) – Design concept Schematic Circuit Diagram

Hey there, In this section, I have made a nice conceptual circuit diagram that will help you to understand how ALU inside the computer works. Schematic Diagram: What is ALU? ALU is a combination of a digital circuit that does the arithmetic operation (like Adding two number, subtracting, multiply, division and logic operation (like AND, OR, NOR, NOT,[…]

Noise-Driven Sound Generator Schematic Diagram

Noise-Driven Sound Generator

The sound generator shown here uses its built-in loudspeaker as a microphone when it is in the standby state. As soon as it detects a noise that exceeds an adjustable threshold level, it becomes active. This small, clever circuit can be used as an alarm generator that reacts to noises. You can also use it[…]
