What else can I help you with?
To send a message in Morse code signal what kind of signal would you have to send?
Binary telephone signals.
What converts a binary signal to analog?
an encoder is used to convert the binary signals into analog signals. the binary signals are fed to encoder section. then these signals are get converted into its equivalent analog signals. Binary DAC.
Are digital signals the only signals that use binary code?
No, digital signals are not the only signals that can use binary code, but they are the most common. Binary code is primarily associated with digital systems, where information is represented using two distinct states (0 and 1). However, binary representations can also be employed in other contexts, such as in certain types of analog signal processing or encoding schemes. Overall, while digital signals are the primary users of binary code, other applications may utilize binary representations as well.
Why is MODEM a necessary component of many data communication system?
because internet that comes down a telephone line are analogue signals and the computer on understands digital signals ( 1 and 0s , Machine code, binary) so the modem translates the analogue signals from the phone line to digital and translates digital signals from the computer to analogue
What travels in a telephone?
Signals.
What ON-OFF or coded signals are referred to as?
Binary.
Why must a modem to be used to transmit binary data through a PSTN?
A modem is necessary for transmitting binary data over a Public Switched Telephone Network (PSTN) because it converts digital signals from a computer into analog signals that can travel over the telephone lines. The PSTN is designed for voice communication, which uses analog signals, so the modem acts as a translator between the digital data and the analog format required by the network. Additionally, the modem ensures that the data can be reliably sent and received, handling modulation and demodulation processes effectively.
How far can cellular telephone signals travel?
Cellular telephone signals can travel up to 22 miles.
What are Communications signals represented in a binary format?
Digital
How is DSL able to carry telephone and data signals at the same time?
Both telephone and data signals can be received at the same time by use of a microfilter. This device increases the data-carrying capacity of the line without disturbing the telephone signals.
How is data retrieved from the telephone?
how is data retrieved from the telephone? the transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. the receiving telephone converts the signals into audible sound in the receiver.
What did the military begin experimenting with when they needed to make their telephone conversations more secure?
Binary telephone code
