Modulation
The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
Digital signals are measured in bits per second (bps).
digital signals have two values. 0 and 1.
well yes and no yes it Will represents letter but as a function of an ASCII code like digital 41 Will represents the letter A
There are dozens of types of signals but two major categories are digital and analogue.Digital signals have descrete voltage levels (if they are binary they represent on and off and may be 3.3V or 0 volts) while analogue signals have continuously varying voltages.
Analogue signals are more vulnerable to error than digital signals. See the related question "Why digital signals are more noise free than analogue signals?" for more details.
modem is the device that carries digital signals
To measure time between digital signals.
