If we use the square wave to transmit digital data (0s and 1s), what will be the data rate. Note data rate is the bits per second. (if two bits contain in one period) 2. Then, if we use the first three components to represent square wave, what is the bandwidth? (Refer to lecture) 3. Consider a noiseless channel with a bandwidth of 3000 Hz transmitting a signal with two signal levels. What can be the maximum bit rate?
