Select the statement that is false. UTP cable is unshielded. Twisting two pairs of wires results in both wire being less affected by external noise. Cat 5 cable is composed of four shielded twisted pairs of insulated wires. O Increasing the number of twists per meter in the Cat 3 cable reduces crosstalk.

Imagine the length of a cable is 2500 metres. If the speed of propagation in a thick co-axial cable is 60% of the speed of light, how long does it take for a bit to travel from the beginning to the end of the cable? Ignore any propagation delay in the equipment. (Speed of light c = 3 x 108 metres / sec)
Please Help ASAP!! JUST ANSWER PART D
We would like to transmit information over a CAT-6 twisted pair cable with a bandwidth of 250 MHz. Calculate the channel capacity (in bps) knowing that the signal to noise ratio SNR is 12 dB (in decibel).
Five channels, each with a l0a-kHz bandwidth, are to be multiplexed together. What is the minimum bandwidth of the link if there is a need for a guard band of 10kHz between the channels to prevent interference?
A Telecommunication channel in form of a copper cable has 4 kHz bandwidth. Calculate the amount of data rate that can be transmitted through this channel if binary signaling is used with raised-cosine pulses and 0.5 roll-off factor.
