A 1000 turns wire are tighly wound on a toroid with a rectangular cross section, the heigh of toroid is 0.5 cm . The inner and outer radii of 2 cm and 3cm respectively. The current in the wire I=100 mA, Ur = 4000. N= 1000, Find H,B,phi and inductance.
Improve the controller designed in part by introducing a mechanism for the disturbance compensation at the plant input. Illustrate advantage of the improved controller by applying the fast varying piecewise constant reference input vector and sinu..
the output voltage of battery drop from 6V .With no load to 5.2V with a load current of 400mA. calculate the internal resistance.
The bellows, diaphragm, and Bourdon tube pressure sensors all exhibit second order time response. This means that a sudden change in pressure will cause an oscillation in the displacement and, therefore in the sensor output.
Analysis of link budget DTH QPSK Satellite link, A direct-to-home satellite television system uses a geostationary satellite in orbit above the equator at a longitude of 109 degrees west.
Assume that an additional inductance can be inserted in series with the load. also assume that the converter has no freewheeling diodes. Calculate the added inductance that leads to a conduction period of 180 degrees when alpha = 30 degrees.
Instead of recreating the design every time we change the instruction ROM, we want to have a way to change the instructions while the system is running. Discuss how the UART can be used to fill an instruction RAM instead
Suppose that a voice signal normally occupies 30 kHz of bandwidth and has a signal-to-noise ratio of 20 dB. Spread-spectrum techniques are used to increase its bandwidth to 2 MHz. (a) What is the signal-to-noise ratio of the spread signal
a. What is the range of the sensor voltage outputs initially and finally? b. What range of voltages would be expected to be measured 2 sec after the step change is applied?
Each pole of a 100kW, 250v flet-compound generator has a shunt field of 2000 turns and a series field of 7 turns. If the total shunt field resistance is 100 ohms
You are working with a design team on a new product and are assigned to design the power supply. The requirements for the power supply are as follows: Input AC: 115 V AC +- 10%, 50-60 Hz Outputs: +5 V DC at 100 ma, +-12 V DC at 50 ma
Suppose a turbine is used for generating electricity, estimate the ratio of powers generated by the same speed water and air. (Water density=1g/cm3, air density =1.2kg/m3)
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
