A series RLC circuit has a resonant frequency of 40 kHz and the Q is 20. At what frequency will the phase angle be 45 degrees?
A potentiometer with a total range of 350° is supplied with a voltage of 12 Vdc. Find the output voltage for an angle of 135°. An absolute optical rotary encoder has five tracks. How many bits is the output
The signal noise ratio in an FM system is 4:1 The maximum allowed deviation is 4 KHz. How much frequency deviation is introduced by the phase shift caused by the noise when the modulating frequency is 650 Hz
an induction motor when connected in delta and started direct on line produces a starting torque of 60Nm and consumes 80A. if the same motor is started using the soft start equipment with the voltage set at 0.8 of the line
False positive and false negative rates can be adjusted, and they are often complementary: Lowering one raises the other. List two situations in which false negatives are significantly more serious than false positives.
a) What is the velocity of the particle b) If this velocity is known to within 0.2% accuracy, what is fx of the position that particle? Assume that the mass of the particle is 2 x 10-26 kg.
The factorial n! of a positive number (integer) is defined by n! = n.(n-1).(n-2)...3.2.1, where 0! = 1. Write a user-defined function that calculates the factorial n! of a number. For function name and arguments use y=fact(x)
Calculate the maximum power that can be sent through an a=2cm , b=1cm air-filled waveguide at 12 GHz such that dielectric breakdown does not occur. Assume that the dielectric strength of air at atmospheric pressure is 3x10^6 [V/m]
A 600V, dc shunt motor has an armature and field resistance of 1.5 ohm and 600 ohm, respectively. When the motor runs unloaded, the line current is 3A, and the speed is 1000 rpm.
A turn contains three blue and seven white chips. A chip is selected at random. If the color of the chip selected is white, it is eplaced and two more white chips are added to the urn.
An overhead line with an inductance of 1.33 mH/km and capacitance of 8.34 nF/km is connected to an underground cable with an inductance of 0.266 mH/km and capacitance of 166 nF/km.
Rain affects the downlink from the satellite and the overall CNR ratio in the receiver falls by 6.0 dB to 13.0 dB. What is the bit error rate and the time between errors now?
Consider the following matrix of expected profits (in units of $1K) versus potential future material price scenarios (P1 - P5), for five different designs (D1 - D5): P1 P2 P3 P4 P5 D1 10 20 30 40 50 D2 20 25 25 30 35
