The final stage of the process is , where mathematics meets decision-making. Detection theory asks: Is the signal actually there? This is rarely a simple "yes" or "no" because noise can often mimic the patterns of a true signal.

A signal is any variable that carries information. In the physical world, most signals are —continuous streams of data like sound waves or light intensity. However, modern technology relies on digital signal processing (DSP) , which requires converting these continuous waves into discrete sequences of numbers through sampling and quantization. The final stage of the process is ,
