Low-Noise Coaxial and multiconductor cables recommended for small-signal application where shielded cable could experience mechanical shock (twisting, crushing, flexing, pulling, etc.) Typical applications include:

If two signal channels within a single data cable share the same signal reference conductor (common return path), the voltage drop caused by one channel’s signal in the reference conductor can appear as a noise in the other channel and will result in interference. This is called galvanic noise.

Coated cable virtually eliminates unwanted cable noise. The EPIC replaceable cable is constructed of high-flex, ultra-low resistance tensile wire, reinforced with a special aramid fiber, and braided for ultimate durability, acoustic transparency, and isolation from mechanical cable noise.

Also see audio noise. Noise is unwanted electrical or electromagnetic energy that degrades the quality of signals and data. Noise occurs in digital and analog systems, and can affect files and communications of all types, including text, programs, images, audio, and telemetry.

When signal cables are involved in the EMI process, this causes a noise in signal circuits. This is aggravated when harmonic currents are present in the system. Higher order harmonics have much higher frequencies than the normal AC wave and result in interference particularly in communication circuits.

In a hard-wired circuit such as a telephone-line-based Internet hookup, external noise is picked up from appliances in the vicinity, from electrical transformers, from the atmosphere, and even from outer space. Normally this noise is of little or no consequence.

Cable Signal Leakage. Cable television systems use radio frequency signals transmitted over cables to provide television and data services to customers. Normally, these RF signals do not cause interference when cable systems comply with FCC rules for limiting interference. Occasionally, however, cable television system signals can “leak.” Cable signal leaks occur when the RF signals transmitted within a cable system are not properly contained within the cable plant.

Troubleshooting for electrical noise. Knowing the types of electrical noise and how to measure them are important first steps in enhancing your ability to troubleshoot.Electrical noise currents on data communication cables are a real problem. They can cause corruption of the desired signals being sent across the cable by the equipment connected to its ends.

Electrical noise occurs or is transmitted into a signal cable system in the following four ways: 1  Galvanic (direct electrical contact) 2  Electrostatic coupling. 3  Electromagnetic induction (in part 4  2) Radio frequency interference (RFI) (in part  2)

what is cable noise
The cable noise is an electrical noise that is picked up by the conductors in a cable. A cable noise is an electrical noise that is picked up by the conductors in a cable.
