Study of different types of Companding Techniques 
The sequence of operations in which PCM is done is
In PCM, the parameter varied in accordance with the amplitude of the modulating signal is
One of the disadvantages of PCM is
The expression for bandwidth BW of a PCM system, where v is the number of bits per sample and fm is the modulating frequency, is given by
In Delta modulation,
In digital transmission, the modulation technique that requires minimum bandwidth is
In Differential Pulse Code Modulation techniques, the decoding is performed by
