## Question 2.13

#### The serial ports on two computers which use binary signalling are connected by a twisted pair cable. The cable has a flat frequency response up to 12 kHz, with negligible group delay distortion.

1. What is the maximum information transfer rate that can be accommodated by the cable, assuming a noise-free environment?
2. If the noise introduced by the cable is –40 dB with respect to the signal power, what is the resulting maximum information transfer rate?
