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