Digital communication techniques lab manual

Verify Nyquist criteria Apparatus:Model ST trainer kit, connection wires, DSO, Power supply. Theory:The signals we use in the real world, such as our voice, are called "analog" signals. To process these signals for digital communication, we need to . Digital communication is a field in which theoretical ideas have had an unusually powerful impact on system design and practice. The basis of the theory was developed in by Claude Shannon, and is called information theory. For the first 25 years or so of its existence. 2.
