1.Explain what is meant by an alternate mark inversion (AMI) code and why this is also referred to as a pseudoternary code. Sketch the AMI waveform for the binary sequence 11010011.

2. A binary sequence 111000111 is to be transmitted on a digital link. Compare the average energies for the following waveforms: (a) polar NRZ-L, (b) Manchester, and (c) AMI. The same pulse width and peak value are used in all cases
