Please, help me correct my "answers". Thank you.The communication channel (ideally) "lets through" frequencies from 450 Hz to 3250 Hz and has a signal / noise (S/N) ratio of 42 dB.

(a)How manysignal elements per second(bauds) is it possible to transfer over this channel?

(b)What is themax. bit rateover this channel?

(c)How do results from(a)and(b)influencemodem's properties?

(a)? Reasoning: you only get 1 crest and 1 trough, hence this theoretical limit? So, if my reasoning is sound, thebaud rate

(b)Depends on number of states each baud (signal) can have. E.g. if a signal can be in 4 states, then each baud "carries" 2 bits, and themax. bit rate= 2 *baud rate.

As we're given the S/N ratio, we can use the equation for the channel capacity:

(c)We divide themax. bit ratefrom(b)by thebaud ratefrom(a)and get the number of bits/baud? That's all?

PS: I see that, instead of repairing the [tex] tag, you've just added the [TEX].
