Continuous-Time Signals

Continuous-time signals represent information that varies smoothly and continuously over time, without interruptions. Think of a clock’s ticking second hand or the sound wave of music—these are signals that change at every moment, not just at specific points. They can be mathematically described with functions that define their value at every instant. Such signals are fundamental in fields like telecommunications and audio processing, where capturing the full range of changes over time is essential for accurate representation and analysis.
