Q. Sampled-data and digital control systems?
These differ fromthe continuous-data systems in that the signals at one or more points of the system are in the form of either a pulse train or a digital code. Sampled-data systems usually refer to a more general class of systems whose signals are in the form of pulse data, whereas a digital control system refers to the use of a digital computer or controller in the system. The term discrete-data control system is used to describe both types of systems.
(a) A second order Sallen and Key Low Pass Active Filter has these component values R 1 =R 2 =15 kΩ, C 1 =C 2 =1 nF and the feedback resistors are R 3 =3.9 kΩ and R 4 =2.3 kΩ
