Consider a permanent magnet dc motor with the following parameters; Ra = 0.35 ohms, La = 1.5 mH, Ke= 0.5(V/(rad/s)), Kt= 0.5 Nm/A and Jm = 0.02kgm^2. The rated torque of this motor is 4Nm. If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
Describe in you own words how a modem works and what steps the data goes through to be sent from one terminal to another via modem.
Draw the logic diagram for the following Boolean expressions. The diagram should correspond exactly to the equation. Assume that the complements of the inputs are not available. a.) XYZ+X'Y'+X'Y'
select a window function to limit the number of samples of an infinite impulse response and the filter specifications are the same, regardless of which window function you select. If you are given the option of using either a Hamming
A full adder is a circuit which adds three bits X, Y, Z together and returns two bits C and S to represent the total as a 2-bit binary number C S. C is the MSB and S is the LSB. For example, if X=1, Y=1, Z=0, the total should be 2, or 102 in binar..
Use the fact that x = 2 and y = 0 at t = 0 to determine the appropriate value of the arbitrary constant in the solution set.
Design a 2-bit counter that, when v = 1, counts in the repeating sequence: 0, 3, 1, 2, and when v = 0, counts in the reverse direction. (a) Construct a state diagram and state table. (b) Implement the counter using D flip-flops.
Rated voltage is applied to the low voltage winding and the high voltage winding is open-circuited. Under this condition, the current into the low voltage winding is 2.4 A, and the power taken from the 2400 V source is 3456 W.
using CodeWarrior write a program to clear Register A, add five to Register A 10 times, and place the result in RAM Location $2000. Use a RAM location for holding the counter
What is the effect of a frequency difference between the carrier and local oscillator on output quality? Show mathematically.
A Na+ ion moves from inside a cell, where the electric potential is -70 mV , to outside the cell, where the potential is 0 V. What is the change in the ion's electric potential energy as it moves from inside to outside the cell
50 kmol per hour of air is compressed from p1 = 1.2 bar to P2 = 6.0 bar in a steady-flow compressor. Delivered mechanical power is 98.8KW. Temperature and velocities are: T1= 300K T2= 520K u1= 10m s^-1 u2= 3.5m s^-1
