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.
Load Balancing and Load Management It has been observed in which the load on all three phases of a distribution line and between the feeders is not balanced. This output in in
Q. If the output signal fromanAMmodulator is given by u(t) = 5 cos 1800 πt + 20 cos 2000 πt + 5 cos 2200 πt , determine: (a) The modulating signal m(t) and carrier c(t). (b)
Note, the armature current is produced in pulses as the armature rotates under the poles, so the torque also pulsates. This can give rise to extra wear on bearings and the engin
