 Analog signal processing

Analog signal processing refers to the manipulation of signals that are represented in continuous time and amplitude. Unlike digital signal processing, which deals with discrete signals and operates using binary values, analog signal processing involves handling real-world signals that vary smoothly over time. These signals can include audio, video, radar signals, and sensor outputs. Key aspects of analog signal processing include: 1. **Continuous Signals**: Analog signals are defined at every instance of time and can take on any value within a given range.
