An advantage of transmitting information using digital signals is A. Digital signals send information very quickly with excellent quality.
A digital signal is a signal that means data as a sequence of discrete values. A digital signal can only carry on one value from a finite set of possible values at a given time. With digital signals, the physical quantity expressing the information can be many things: Variable electric current or voltage line.
Digital signals can transmit information with less noise, distortion, and interference. Digital circuits can be reproduced easily in mass amounts at comparatively low costs. Digital signal processing is more flexible because DSP operations can be changed using digitally programmable systems.
Digital signals can be transmitted over transmission lines using either serial or parallel transmission. With serial communication, the sequence of bits used to represent a value is sent in sequence along a single transmission line.
