How a transformer works and apply those rules to a transformer where the primary core cross-sectional area is twice.
The flux density (B) is a linear function of the current for both the primary and secondary. Since the primary cross-sectional area is twice that of the secondary, it produces twice the flux (BxA) at the same current. So to cancel out the secondary flux of a 1:1 transformer, the primary only needs to drive half the current of the secondary. This means VxI of the primary is half that of the secondary creating the impossible result of efficiency equals 200%.
A system is described by the impulse response h(t) given in the following problems. Compute and plot the response of the system to the input signal x(t). (a) h(t) = t; 0

What is the power level entering the first active stage of the receiver at 1900 MHz being fed by a 25 meter coax with a loss of 20 dB/km, given that the Isotropic Receive Level is -134 dBW and the receiving station has a 1 meter radius dish
design a decade counter which counts in the sequence: 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 0000 draw a complete state diagram for the counter of (b) showing what happens when the counter is started in each of the unused states
Consider a discrete time LTI system with impulse response given by h[n] = u[n + 2] - 2u[n - 1] + u[n - 4]. A. Determine the transfer function H(z) for this system. B. Determine the z transform Ys(z) of the step response for this discrete time LTI ..
A four-pole three-phase synchronous generator has Xs = 1.82 per unit and ratings of 60 Hz, 24 kV, and 650 MVA. The generator operates at the following point: 60 Hz, armature voltage of 24 kV, output apparent power of 650 MVA
two identical CE amplifiers are connected in cascade. The first stage is fed with a source eVsig having a resistance Rsig= 10k ohms. A load resistance Rl=10K ohms and is connected to the collector of the 2nd stage.
