A coil of 5000 turns is wound on to a nonmagnetic toroid of csa 100 cm2, and mean circumference 0.5 m. A second coil of 1000 turns is wound over the first coil. If a current of 10 A flows through the first coil, determine
(a) the self-inductance of the first coil,
(b) the mutual inductance, assuming a coupling factor of 0.45, and
(c) the average emf induced in the second coil if interruption of the current causes the flux to decay to zero in 0.05 s.
The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 40o; then it is commanded to go to 22o. What is the error when the arm position is at 15o
Compare the frequency response magnitudes for each of the responses above (will need to plot on a logarithmic scale). Comment on the observations noting things such as if the signals are resolvable, the size of the side lobes, etc.
Design a minimum order IIR digital filter that will pass the first component of xa(t) with attenuation of less than 1 dB and suppress the second component to at least 50 dB. The filter should have a monotone passband and an equiripple stopband. De..
A fluid flows through a turbine at the rate of 45 kg/min. Across the turbine the specific enthalpy drop of the fluid is 580 kj/kg and the turbine loses 2100 kj/min in the form of heat energy. Determine the power produced by the turbine.

If an RC circuit is supplied with 24 VDC and the circuit is in its third time constant, how much voltage wouldbe present across the capacitor
Charged line and multiple conducting planes. An infinitely long line charged with a charge density PI is located at a distance d from a very large conductor, as in Figure 5.38.
design a 100 hp motor controller circuit which has a push button to start and stop the motor. include an external cooling fan and a means to automatically shut down the motor is it overheats. Hint attach thermostat to case of motor.
What is the shape of the spectrum of the signal? What is the extent of the spectrum in the frequency domain? What is the unit that is applied to the magnitude of the spectrum?
Your task is to work in a group to prepare a report on: Description of the selected product or component Identification of the property requirements for the application
For a particular inverter design using a power supply VDD with VOL = 0.2VDD, VOH = 0.6VDD, VIL =0.4VDD, and VIH = 0.3VDD. In order to maintain noise margins of at least 0.15V for both noise marginhigh (logical 1) and noise margin low (logical 0), wha..
An automatic automotive spray painting system consists of conveyors, spraying, dust and overspray extraction fans with electrostatic and water walls, finishing with baking ovens. This system is connected to a 415V, 50 Hz three phase and has been divi..
