It is desired to construct a 64K × 16 RAM from an available RAM chip specified as 16K × 8. Determine the number of RAM chips required for the same.
Compute the unit-pulse response h[n] for the discrete-time system y[n+2]2y[n+1]+y[n]=x[n] (for n = 0, 1, 2, 3).
Determine the transition point. - Determine vO for vI = 3.3 V. - Repeat part (a) for RD = 30 k. - Repeat part (a) for RD = 5 k.
A 92in*24in*32in, 450kg Square D motor controller is used to drive a 1600 hp,2400V,3-phase,60Hz squirrel-cage motor. a. assumeing the motor has a minimum efficiency and power factor of 96%and 90%,respectively
A synchronous motor is connected across the load to improve the total power factor to unity. The synchronous motor is running unloaded (no mechanical load). If the synchronous reactance of the motor is 10Ω, compute the equivalent field voltage of ..
The transformer draws a current of 3 A, and the power is 100 W when a 100-V supply is impressed on the low-voltage winding with the high-voltage winding open-circuit.
A steel wire 30 ft long, hanging vertically, supports a load of 500 lb. Neglecting the weight of the wire, determine the required diameter if the stress is not to exceed 20 ksi and the total elongation is not to exceed 0.20 in. Assume E = 29 × 106..
This same optical sensing technique is used in many mice to detect movement of the mouse ball. Use the position feedback to implement more accurate variable speed and position control for the motors.
Design a 3-stage MOSFET amplifier that provides a differential gain |vo/vd| > 20V/V, a small common-mode gain, and an output resistance Ro >1kΩ. The amplifier is to drive a load RL = 10kΩ. The frequency of the signal source is 10 kHz.
Suggest how a new plate could be made to ensure transmission is achieved at only one of these wavelengths.
Assume the resistance of a human person was 500 ohms, if a person was struck by lightning with a peak voltage of 100,000 volts, what was the peak current that would flow through the person
For the circuit of given figure, find Vab if (a) k = 0 and (b) k = 0.01. - Do not use network theorems to simplify the circuit prior to solution.
Why very high resistance wire is used is field windind and low resistance wire is used in armature winding in DC shunt machine?
