a modem
The hardware used to convert the digital signals of a computer to signals that can be transmitted is called a modem (modulator-demodulator). It converts digital data from the computer into analog signals for transmission over telephone lines or cable systems. Additionally, network interface cards (NICs) and routers can also play a role in this process by facilitating data transmission over local networks and the internet.
MODEM:A modem takes digital signal from computer and converts them to analog for the phone and reconverts them back
A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.
Yes, a modem (modulator-demodulator) converts digital signals from a computer into analog signals that can be transmitted over various types of networks, such as telephone lines or cable systems. It also performs the reverse function, converting incoming analog signals back into digital form for the computer. This process enables communication between digital devices and external networks.
it is an DAC (Digital to analogue converter
yes
no it dont
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.
Digital signal is moreefficientimmune to noiseerror freethan analog signal.
