A single-phase 10 kVA, 2300/230V two-winding transformer is connected as an autotransformer to step up the voltage from 2300 to 2530V.
a. Draw the schematic diagram of the autotransformer showing the winding connections and all voltages and currents at full-load.
b. Find the kVA rating of the autotransformer. Do not allow the currents of windings to exceed their rated values.
Let x[n] be a finite sequence that is nonzero for n [N1, N2], and h(n) be a finite sequence that is nonzero n [N3, N4]. Answer the followings: a. For fixed n, what is the range of k that makes h(n-k) nonzero

show that the resistivity of intrinsic Ge at 300k is 44.44 ohm-cm. If donor impurity is added to an extent of 1 atom per 10^8 Ge atoms, prove that the resistivity of the Ge sample drops to 4.42 ohm-cm (at 300k).
Air enters an adiabatic nozzle steadily at 300 kPa, 20076;C, and 30 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm2. Determine (a) the mass flow rate through the nozzle, (b) the exit temperature of the air
Suppose a cache can satisfy a processor request in 5ns if it has a hit; otherwise the memory access time of 20ns must be added to the hit time. What is the average access time seen by the processor core for instructions for miss rates of 5%, 2% an..
Design a Moore machine that has one input X and one output Z. Provide a complete design using D Flip flops. In this design, the output should be 1 any time the sequence 01101 occurs. Overlapping sequences are allowed.
