An AND circuit, also known as an AND gate, is a fundamental building block in digital electronics. It's a type of logic gate that produces a high output (typically 1) only if ALL of its inputs are high (1). If even one input is low (0), the output will be low (0). Think of it like a door that only opens if ALL the keys are turned. 🔑 It's essential for performing logical operations in computers and other digital devices.
