Chapter 20: Problem 2723

What is the frequency range of signals that can be transmitted in care of twisted pair of wires ? (A) \(5 \mathrm{MHz}\) to \(20 \mathrm{MHz}\) (B) \(5 \mathrm{MHz}\) to \(10 \mathrm{MHz}\) (C) \(100 \mathrm{~Hz}\) to \(4 \mathrm{MHz}\) (D) \(5 \mathrm{MHz}\) to \(20 \mathrm{MHz}\)

Short Answer

Expert verified
The correct frequency range of signals transmitted through a twisted pair of wires is \(100 \mathrm{~Hz}\) to \(4 \mathrm{MHz}\) (Option C).

Step by step solution

01

Option A

The first option is a frequency range of \(5 \mathrm{MHz}\) to \(20 \mathrm{MHz}\). This range is too high for standard twisted pair wires used in most Ethernet connections. This signals us that option A is likely not the correct answer.
02

Option B

The second option is a frequency range of \(5 \mathrm{MHz}\) to \(10 \mathrm{MHz}\). While this range is lower than option A, it's still not the correct range for standard twisted pair wires used in Ethernet connections. We can eliminate option B as well.
03

Option C

The third option is a frequency range of \(100 \mathrm{~Hz}\) to \(4 \mathrm{MHz}\). This is indeed the correct frequency range for twisted pair wires used in most Ethernet connections, such as the popular CAT5 and CAT6 cables. Therefore, option C is the correct answer.
04

Option D

The fourth option is the same as option A, with a frequency range of \(5 \mathrm{MHz}\) to \(20 \mathrm{MHz}\). As discussed earlier, option A is not the correct frequency range for twisted pair wires. Hence, option D is also incorrect. In conclusion, the correct frequency range of signals transmitted through a twisted pair of wires is option C, \(100 \mathrm{~Hz}\) to \(4 \mathrm{MHz}\).
