Coax is normally used in high frequency applications due to its ability to shield the signal. The coax construction prevents radiation, while at the same time prevents noise pick up. It is the shielding that makes coax a better choice at higher frequency, however coax can be used as low as audio frequencies.
Lower frequency systems do not need the shielding due to the long rise times. They are not as sensitive to noise pick up and generally do not radiate.
What else can I help you with?
How t convert high frequency into low frequency?
To covert a high frequency to a low one, we use flip-flops.
What is alpha cut of frequency?
it is the frequency at which the current amplification drops 3dB below its low frequency value.
What is a padder capacitor?
Padders are a type of Capacitors which are used at low frequency end of the radio dial.
What is the use of capacitor before input of power supply AC?
They are used to offer a low impedence path to high frequency interference from switching sources such as fridges and thermostats. Also to curb radio frequency breakthrough.
What is h parameters transistor?
Hybrid Parameters are the values which is used to find FREQUENCY RESPONSE of a low frequency transistors. you may have doubt like why we are using only H-PARAMETERS why not HYBRID-PI models because..., h-parameters values are constant at low frequency moreover, at low frequency transition model we have assumed that the response of transistor to changes of input current or input voltage is instantaneous this is the reason why we had neglected shunt capacitances . as there were no shunt capacitances there is no chance of using hybrid-pi model. i hope you got answer for your question
What does 'coaxial cable' mean?
The term coaxial comes from the inner conductor and the outer shield sharing ("co-") the same axis. It is often used as a high-frequency transmission line to carry a high-frequency or broadband signal but may also be used for frequencies as low as audio frequency.

Where can I get a coaxial cable for a low price?
Purchasing from Amazon.com would provide you with the lowest price for the coaxial cable. They have many different brands and lengths of cable from which you may choose.
Why does tv coaxial cable not give shock?
The voltage is too low.
What is the error rate of coaxial cable?
The bit error rate is a standard transmission-error rate of a medium such as copper wire, coaxial cable, or fiber-optic cable. Coaxial cables have a low error rate that is generally 1 in 1 billion bps.
What is function of coaxial cable?
coaxial cable has a solid copper or copper-clad-steel centre conductor surrounded by a non-conductive dielectric insulating material. The dielectric is surrounded by foil shield/s and/or copper braid/s which form the outer conductor and also shield against electromagnetic interference (EMI). The outer conductor/shield is encased in a PVC jacket.
What is 412 coax cable?
412 coax cable, commonly referred to as RG-412, is a type of coaxial cable used primarily in radio frequency (RF) applications. It features a solid copper center conductor, surrounded by a dielectric insulator, a braided shield, and an outer jacket, which provides durability and protection. RG-412 is known for its low loss and high-frequency capabilities, making it suitable for use in telecommunications, satellite systems, and broadcast applications. Its specific design allows for effective signal transmission with minimal interference.
What does cables mean?
The term coaxial comes from the inner conductor and the outer shield sharing ("co-") the same axis. It is often used as a high-frequency transmission line to carry a high-frequency or broadband signal but may also be used for frequencies as low as audio frequency.
What is the difference between baseband coaxial and broadband coaxial cable?
The difference between baseband coaxial and broadband coaxial cable is baseband coaxial technology uses digital signaling in which the cable carries only one type of digital signal. Where as the broadband coaxial technology typically transmits analog signals and is capable of transmitting multiple frequencies of data simultaneously.
What does CCER stand for dealing with coax cable?
CCER stands for Coaxial Cable Electrical Resistance. It refers to the measurement of resistance in coaxial cables, which is crucial for assessing their performance in transmitting signals. Low electrical resistance is desirable, as it indicates minimal signal loss and better overall efficiency in communication systems.
What type communication cable can only be used in a dwelling?
The communication cable that can only be used in a dwelling is typically "low-voltage" cable, such as Category 5e (Cat5e), Category 6 (Cat6), or coaxial cable designed for residential use. These cables are intended for internal wiring within homes to support data and telecommunications services. They are not rated for outdoor use or for installation in commercial buildings, where different standards and cables are required.
What is the major factor that makes coaxial cable less susceptible to noise than twisted-pair cable?
A coaxial cable is shielded from electrical interference signals whereas UTP (Unshielded Twisted Pair) cable is not. The random twisting with which UTP is manufactured works very well, however, in locations where the interference levels are relatively low, because its method of construction ensures that any interference affects both wires in the pair equally. It should also be mentioned that STP (Shielded Twisted pair) cable is also available and is sometimes specified for LANs (Local Area Networks) instead of coaxial cable. But the much greater volume of coaxial cable sold means that coaxial cable prices have been kept very competitive with STP. As STP tends to be more tricky to install - its shield has to be very carefully and correctly terminated at each end - coaxial tends to be used more than STP where noisier-than-normal interference conditions are present at a particular site. Since the 1990s NIC (Network Interface Card or Component) equipment has had extra logic cicuits within it to reject ambient interference much more effectively than equipment which was designed in the previous 20 years, so nowadays UTP can be used more extensively in locations where only STP or coaxial cable would have had to be used before. So, in relation to LANs in normal non-industrial office and domestic buildings, this exam question is now almost obsolete! However coaxial cable is still necessary to carry LANs in difficult environments such industrial plants; hospitals; undergound railway and road tunnels and mines; on board ships and aircraft, etc. and must also be used to carry signals for radio, televison, video and other applications which run at much high frequencies and bandwidths than LANs.
