They can be trasmitted
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.
Actually you have this backwards, the telephone lines can only carry analogue signals (voice band, 20Hz to 3KHz) not digital signals.The device that converts digital signals to analogue signals for transmission over telephone lines is called a phone MoDem(this stands for phone modulator demodulator). At the opposite end of the line it of course converts the telephone analogue signals back to digital signals.
With analog and digital signals.
Yes, via satellite (phone).
it is baseband transmission
Transmission channels are defined as paths through which electrical signals can pass through. It may be in form of a physical cable.
It's called a direct transfer transmission. It involves contact of an infected person with a susceptible person and the physical transfer of organisms.
For example, personal digital assistants and cellular telephones communicate with desktop computers through data transfer.
