Digital Transmission , conversely, is the modern standard for computer networks. It deals with discrete pulses. While digital signals suffer more from attenuation over long distances, they possess a distinct advantage: the ability to be regenerated. Unlike amplifiers, digital regenerators can distinguish the signal from the noise. They can reproduce a clean, original signal, effectively eliminating any accumulated noise. This makes digital transmission more reliable and secure, as well as easier to encrypt and multiplex.
