Introduction to Data Encoding & Digital Signals

A digital signal represents these bits using discrete, distinct voltage levels or light pulses. For instance, a high voltage might represent a '1', and a low voltage might represent a '0'. The advantage of digital signals is their resilience: as long as the receiver can distinguish between these distinct levels, noise (interference) won't easily corrupt the data. Analog signals, in contrast, use a continuous range of values, making them more susceptible to noise.
