Analog Electronics

Analog electronics is a fundamental branch of electrical engineering that deals with continuous-time signals, where information is represented by physical quantities like voltage or current that vary smoothly over a continuous range. In contrast to digital electronics, which uses discrete states, this field focuses on the design and analysis of circuits using components such as resistors, capacitors, inductors, transistors, and operational amplifiers. These components are combined to perform essential functions like amplification, filtering, signal generation, and power conversion, forming the basis for countless applications in audio systems, radio communications, sensor signal conditioning, and power management.
