A series connected DC motor has R_F + R_A = 11.5 ohm and draws 1 A of current from a DC voltage source with V_T = 18 V while running at 1000 rpm. What is the speed and developed torque when drawing 0.75 A of current?
Compute the polar form of the impedances shown below in rectangular form in parts a and b, and compute the rectangular form of the impedances shown below in polar form in parts c and d
It is required to use a peak rectifier to design a dc power supply that provides an average dc output voltage of 15 V on which a maximum of 1-V ripple is allowed. The rectifier feeds a load of 150 ohm.
a) construct the straight-line Bode plot of the gain. Is this a low-pass, high-pass, bandpass, or bandstop function b) Use the straight-line plot to estimate the maximum gain and the frequency at which it occurs.
1. Use the Quine-McCluskey minimization method to find a minimum cost SOP realization of the following functions (a) f(x1,x2,x3,x4)= fm(0,2,4,5,7,8,9,15) (b) f(x1,x2,x3,x4)= fm(0,4,6,8,9,15) + d(3,7,11,13)
(Probability of negative lifetime is negligible) Lifetime of chip 2 is also a Gaussian RV with mean 22,000 and standard deviation 1000 hours. Which is preferred if the target lifetime of the system is (i) 20,000 hours and (ii) 24,000 hours
TDMA has 416 frequencies in one of the cellular license bands. If a cellular operator designs a network with a 5/15 reuse pattern, how many frequencies per cell (sector) can be supported? ( ignore control channels)
A semiconductor company has the following costs associated with Product X: - Fixed cost of $1B ($1,000,000,000) - Die cost of $6 at a die yield of 50% - Testing and packaging cost of $3 per die - A final test yield of 90% with a product volume of 500..
When the scope probe is properly calibrated, it can be modeled as a 9[M Ohm] resistor in parallel with a capacitor having a capacitance l/9th that of the oscilloscope input capacitance.
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.
Assuming that the secondary is open-circuited and that the primary is connected to a 13.8-kV source, calculate the magnitude and phase angle (with respect to the high-voltage source) of the voltage at the secondary terminals.
An otherwise-ideal op amp, known to have an open loop gain of 10^4 V/V , is measured in a circuit to have an output voltage of -3 V. While it would be difficult to measure, what would you expect the voltage from the negative terminal
Reduce the equation to the slope-intercept form and give the slope and the y-intercept.
