In digital circuits modem is used to multiplex and demultiplex the digital data.multiplexing means the digital signals amplitude or frequency or phase is varied with a carrier signal.at the receiver end the carrier signal is separated out and original digital signal is received

Why the synchronous modems are more costly than the asynchronous modems?
Because they contain clock recovery circuits
What are three different types of digital modems?
There are ISDN, DSL and Cable
What are electronic and mechanical equipment called?
Digital circuits are the most common physical representation of Boolean algebra and are the basis of all digital computers. Computer's industrial processes are constructed of digital circuits.
Is the intigrated circuit is an analog or digital device?
Both. An IC (integrated Circuit) is a compact form of several electronic circuits. These circuits may be analog or digital.
In telegraphy how you are using frequency shift keying?
Like in modems, you make digital zeros one frequency and digital ones another frequency.

Can 555 timer be considered a digital device?
You can use it in both analog and digital circuits but it is considered as a digital device.
Are telephone company circuits now digital?
Yes.

What are the differences between analog and digital modems?
Analog modems use the telephone cable to send audio signals, which represent 1's and 0's over a connected phone line, using phone voltages. Digital modems use a high frequency signal with the data superimposed on it. They can use the copper phone wires like an antenna. In this way there does not have to be phone connection in use. The phone can be used as well as the signal, if a filter is used to stop interference. Digital modems can also use fibre optic or coaxial cables.
How can you convert the digital to analog or analog to digital?
Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv
