Problem
1. If a telephone line can carry a signal with a baud rate of 6000 and we want to transmit data at 33,600 bps, how many different signal levels will be necessary? Is this how a 33,600-bps modem operates?
2. Can modems and codecs be used interchangeably? Defend your position. (The modem converts digital data to analog signals and back to digital data; the codec converts analog data to digital signals and back to analog data.}
