QUESTION 28 An engineer has designed transmission equipment to transmit 7200 symbols per second while encoding 8 bits per symbol. If the signal to noise ratio is 400:1 and the channel bandwidth is 3625 Hz, has the engineer's design exceeded theoretical limits? O Yes, both the limit on symbol rate and the limit on bits per symbol have been exceeded. O Yes, but only the limit on symbol rate has been exceeded. O Yes, but only the limit on bits per symbol has been exceeded. O No, none of the theoretical limits have been exceeded.
