How does a wireless coaxial cable transmitter work to transmit signals without the need for physical connections?

A wireless coaxial cable transmitter uses radio waves to send signals without needing physical connections. The transmitter converts electrical signals into radio waves, which are then transmitted through the air to a receiver. The receiver picks up the radio waves and converts them back into electrical signals for use. This allows for communication without the limitations of physical cables.


What difference between copper cable and optical cable?

A copper cable transports electrical signals. An optical cable transports light signals.


What is core of cable?

The core of a cable is the central part where the electrical conductors are housed within the cable. It is surrounded by insulation and protective layers to ensure the safe transmission of signals or power through the cable.


Is a moderm converts the digital signals from a computer into signals that can travel over a network?

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.


How optical jack works?

An optical jack, often referred to as a TOSLINK or optical audio connector, transmits digital audio signals using light. It employs a fiber optic cable to convert electrical audio signals into light pulses, which then travel through the fiber. At the receiving end, a photodetector converts the light back into electrical signals, ensuring high-quality audio transmission with minimal interference. This method allows for high-fidelity sound over longer distances without degradation.


Is a modern an output device?

A "modem" is considered a transceiver. It receives data, and sends data. But it also converts signals in the sense that it can be seen as a DAC (digital to analog converter) and a ADC (analog to digital converter). Most dialup, DSL, and cable modems are examples of that - they plug into your computer and converts from-and-to your ISP the data you're receiving and sending. The signals you send from your computer are typically digital and the modem converts them into analog ones.


How do vibrations pass through microphone?

When sound waves reach a microphone, they cause the microphone diaphragm to vibrate. These vibrations are then converted into electrical signals by the microphone's transducer, typically a coil or capacitor. The electrical signals are then transmitted through the microphone cable to a recording device or amplifier.


Would you recommend coax cable for running power to an outdoor lamp post?

No, coaxial cable is not suitable for running power to an outdoor lamp post. Coax cable is designed for transmitting data signals, such as cable television or internet, rather than electrical power. For outdoor electrical applications, it's better to use outdoor-rated electrical wire, such as UF (underground feeder) cable, which is specifically designed to handle power and withstand environmental conditions.


Different between fiber optical cable and copper cable?

Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.


Do Fiber-optic cable send or receive electrical signal?

No. Fibre optic cables use light instead of electrical signals. Depending on the function of the optical fibre either a laser or an LED will be used.


What are the basic functions of a Cable?

I'm not to good at wires but I know that one basic function would be that it transmits data from point A to B


What is SPDIF?

S/PDIF or Sony Philips Digital Interconnect Format is a standard/protocol that specifies transmission of audio signals from one device to another in digital format. Both coaxial electrical cable and an optical fiber cable can be used to carry signals in S/PDIF format. - Neeraj Sharma
