What else can I help you with?
What metals are in alarm clocks?
digital alarm clocks have copper but analog clocks depend on who made it
What type of signal uses existing telephone copper wires to send and receive?
both analog and digital.
What element of the PSTN is most likely capable of transmitting only analog signals?
The local loop is the part of the PSTN most likely to still use copper wire and carry analog signals.
What are the types of analog signal?
An Analog Signal is a continuous signal, just like an electric current that flows through the copper cables when your electrical appliances are turned on. This continuous signal represents physical measurements. An example of this would be with an analog audio signal, the voltage amount of the signal changes continuously with the change in sound waves. Analog Signals are normally represented as electrical signals, but there is also Classical Mechanics, Pneumatics, and Hydraulics technique's that can be used in analog signals.
What kind of lines consist of two digital channels over the same copper wire used by regular analog telephones?
Integrated Services Digital Network (ISDN) lines
Does the connection between your home and the end office local loop use an analog or digital signal?
It depends. It's true, the standard POTS (plain old telephone service) is delivered over an analog loop. However, you may have a service known as DSL, it is even in the name (Digital Subscriber Line) digital. It uses the *unheard* areas (25kHz+) of the line to carry digital signal. So a line can be both analog and digital! Also, DSL can be provided on what's called a "dry loop" which is using a pair of copper (typically what would carry POTS service, but isn't connected to the PSTN.) That being said, it can be Analog, Digital or both: Analog and Digital.
What is the full form for DSL?
DSL stands for Digital Subscriber Line and it is a name given to the communication technology using PSTN telephone copper wire. In this digital signals from digital computers are converted into analog form by DSL modem and transmitted via copper lines and at the receiver a demodulator transforms it back to digital form(binary).
How does IDSL internet work?
IDSL is a system in which digital data is transmitted at 128 Kbps on a regular copper telephone line (twisted pair) from a user to a destination using digital (rather than analog or voice) transmission, bypassing the telephone company's central office equipment that handles analog signals. The trick is, a special router is placed at the phone company's central office, giving it the ability to send a digital signal over an analog line.
What part of the telephone network depends on analog signals?
In traditional telephone networks, the local loop, which connects individual homes and businesses to the central office, primarily relies on analog signals. These analog signals transmit voice communications over copper wire. While much of the backbone and long-distance transmission has shifted to digital formats, the last mile connection often still uses analog technology, especially in legacy systems. However, many newer systems are transitioning to digital methods for improved efficiency and quality.
How does the copper backing plate provide dc power to the circuit board through the sandwiched foam?
I'm not at all sure what you are describing. If the "sandwiched foam" you mention is plastic foam between the circuit board and the copper plate then the copper plate has nothing at all to do with power, the copper plate is just a shield to prevent radiation and/or interference. This shield has one connection to ground and no other connections.Power is provided in a circuit board by internal traces and/or planes: digital ground, digital +V, analog ground, analog +V, analog -V. Sometimes boards use external power bars that are soldered to several pads on the board, each power bar has 2 or 3 conductors inside it and is semirigid. Power is not provided to a circuit board by an external copper plate.
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.
Can copper wires carry digital information?
Yes, this is done all the time. Category 5, category 5e, and category 6 are the most common copper cables used at this time. They are basically advanced versions of the original phone cable. Coax cable is another type of copper cable used to carry digital information. It is the cable the satellite dish and cable companies use and the most common type is RG-6. This cable is capable of faster data transfer speeds than the phone type cables.
