Baud Rate Problem

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

Some computers need to have large numbers of RS-232 lines (e.g. servers or Internet providers). For this reason, plug-in cards with multiple RS-232 lines exist. Suppose that such a card contains a processor that must sample each incoming line at 8 times the baud rate to see if the incoming bit is a 0 or a 1. Also suppose that such a sample takes 1 usec. For 28,800-bps lines operating at 3200 baud, how many lines can the processor support? Note: The baud rate of a line is the number of signal changes per second. A 3200-baud line can support 28,800 bps if each signalling interval encodes 9 bits using various amplitudes, frequencies and phases. 56K modems do not use RS-232, so are not a suitable example of RS-232 timing.

Number of lines required = 28,800*3200*10^-6 lines

I have a question where did the 10^6 come from? I am trying to figure on how this problem was solved.

Baud Rate: It's the number of signal changes per second.
Baud: The baud, indicates the number of bits per second that are transmitted.

For example, 3200 baud means that 3200 bits are transmitted each second. At higher speeds, it is possible to encode more than one bit in each ...

Solution Summary

QPSK / Multiplexer

Need help with a QPSK / Multiplexer question. please see attached. thank you.

Additional information has been provided for this question: There are 20 sources. Each source transmits at 32kbps. (This means that each source is either sending 32kbps or its sending nothing.) Each source only transmits 20% of the time.

(note: if you are confident you can help with more than one of my postings, please let me know and I will restrict the ones you choose for you - thanks).
