•With today's technology, what improvements could be made in the wiring in the applications you selected?
Describe the how the Hall Effect it is used to measure whether a semiconductor material is n-type or p-type. Sketch a diagram and show the critical measurements.
A certain cache has an access time of 2 nanoseconds and a hit percentage of 95%. If the main memory access time is 8 nanoseconds, what is the average access time for a read operation?
If the voltage drop across the capacitor is 115 volts and the power taken by the circuit is 922 watts, calculate a) the circuit current, b) the ohmic value of the resistor, c) the line voltage, d) the circuit power factor
compute the power loss in a transmission line with a resistance of 0.05 ohms/mile. Compute the power loss if 500kW of power is transmitted from a power generating station to cities at distances of 20,30,40....100 miles at 100v and 200v.
Asuuming that an 8-bit ADDC channel accepts analog input ranges from 0 to 12 volts, determine the following: a) number of quantization levels b) step size of the quantizer c) Quantization level when the analog voltage is 9.25 volts
Plot the signal x(n) 0
Consider the signal x(t)=e^-at where a is a positive number. Determine the Fourier Transform of and plot both the magnitude and the phase angle as a function of the frequency.
A 150 MHz uniform plane wave in normally incident from air onto a material whose intrinsic impedance is unknown. Measurements yield a standing wave ratio of 3 and the appearance of an electric field maximum at 0.3 wavelengths
On a spacecraft two engines fire for a time of 541 s. One gives the craft an acceleration in the x direction of ax = 4.90 m/s2, while the other produces an acceleration in the y direction of ay = 7.60 m/s2.
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal)
A three phase Y-connected 220-Volt 10-Hp, 60Hz, 6-pole induction motor has the following constants in Ohms per phase referred to the stator. R1=0.294, R2=0.144, X1=0.503, X2=0.209, Xm=13.25.
Design an interface for a ±24 V, 500 mA geared DC motor. The time constant of the motor is 10 ms. Include software to adjust the delivered power from 0 to 100%.
