3) What transmission impairment(s) are improved when moving from twisted pair to coax cable.

Solution

When moving from twisted pair to coax cable, transmission impairments related to noise are improved.

The interference by noise is lesser in coax cable than in twisted pair cable. Coax cables tolerate interference better than twisted pair cables.

Also, coax cable carries signals of higher frequency ranges than twisted-pair cable.
