Q. Explain Continuous-data and discrete-data systems?
A continuous-data system is one in which the signals at various parts of the systemare all functions of the continuous-time variable t.When one refers to an ac control system, it usually means that the signals in the system aremodulated by some kind ofmodulation scheme.On the other hand, a dc control system implies that the signals are unmodulated, but they are still ac signals according to the conventional definition. Typical components of a dc control system are potentiometers, dc amplifiers, dcmotors, and dc tachometers; typical components of an ac control system are synchros, ac amplifiers, ac motors, gyroscopes, and accelerometers.
