Chapter 20: Problem 2686

Coaxial cable offers a band width approximately \(\mathrm{MHz}\) (A) 1 (B) 20 (C) 250 (D) 1000

Short Answer

Expert verified
The correct answer is option (C) with a bandwidth of 250 MHz, which is more in line with what is expected from typical coaxial cables in modern communication systems.

Step by step solution

01

Option Elimination

To determine the correct answer, we can use our knowledge of coaxial cable properties and the concept of bandwidth in communication systems.
02

Evaluate Option (A)

Option (A) suggests a bandwidth of 1 MHz. Most coaxial cables used in communication systems typically offer higher bandwidth than this, making this option unlikely to be correct.
03

Evaluate Option (B)

Option (B) suggests a bandwidth of 20 MHz. This value might be found in older cable systems. However, modern coaxial cables can offer significantly higher bandwidths.
04

Evaluate Option (C)

Option (C) suggests a bandwidth of 250 MHz. This value is more in line with what would be expected for a coaxial cable in modern communication systems. Coaxial cables are widely used in cable television (CATV) systems and offer high bandwidth to accommodate multiple channels and internet connections.
05

Evaluate Option (D)

Option (D) suggests a bandwidth of 1000 MHz (1 GHz). This value is higher than typical coaxial cable bandwidths. While some specialty coaxial cables might offer such high bandwidth, it is not common for general use.
06

Select the Correct Answer

Based on the evaluations of each option, the most likely correct answer is option (C) with a bandwidth of 250 MHz, which is more in line with what is expected from typical coaxial cables in modern communication systems.
