A 2200-V, 1000-hp, three-phase, 60-Hz, 16-pole, wye-connected, wound-rotor induction motor is connected to a 2200-V, three-phase, 60-Hz bus that is supplied by synchronous generators. The per-phase equivalent circuit of has the following parameters: R1 = 0.1 = R 2, Xl1 = 0.625 = X l2, and Xm = 20 .Ifthe machine is driven at a speed of 459 r/min to act as a generator of real power, find the rotor current referred to the stator and the real and reactive power outputs of the induction machine.

A symmetrical fluctuating message, with |f(t)| max = 6.3 V and KCR = 3, is to be encoded by using an encoder that employs an 8-bit natural binary code to encode 256 voltage levels
Q. Basic introduction of Analog Building Blocks? Electronic systems usually process information in either analog or digital form. In order to process the two different kinds of
how can yuo calculate voltage,curent basing on the meter bridge?
1) Assume that we are given the continuous-time signal xa (t) = xa1 (t) + xa2 (t) + xa3 (t), where, xa1 (t) = 2 + cos3 (2pf1 t + p 3 ) + 2 cos(2pf2 t), xa2 (t) = 2 cos(2pf3 t)
