Since Signals Are Discrete, We Preserve Exact Values—Why This Matters in Data Accuracy In the world of digital signal processing and communication systems, one fundamental principle shapes how we interpret and manipulate information: since signals are discrete, we keep the exact value. This simple yet powerful fact underpins the precision and reliability of countless technologies, from digital audio and video to wireless communications and sensor networks. ### Understanding Discrete Signals Discrete signals differ from their continuous counterparts in that they represent information at distinct, separable points in time or space—essentially, a finite set of values. Unlike analog signals, which vary continuously across a spectrum, discrete signals consist of measurable, isolated samples. This discrete nature is foundational in digital systems, where analog inputs are converted to binary data, preserving exact values without approximation.
