Design a device which will input two 4-bit unsigned numbers and subtract twice the smaller of the two numbers from the larger of the two numbers (That is, input x and y and output x - 2y if x > y and output y - 2x otherwise.) Use the following devices we've studied (n-bit adder/subtractor, n-bit comparator and MUXes as well as combinational gates in your design.
he windings of a large electromagnet have an inductance of 10.0 H and a resistance of 8.00 Ohm. The electromagnet is connected to the external EMF of 230 V. After electromagnet is switched on
What are the main characteristics of the core : 1) of a step-index multimode optical fiber 2) of a graded-index multimode optical fiber 3) of a single mode optical fiber
explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the precise mathematical definitions
A 480 V permanent magnet ac motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 ohms per phase. Core losses are 100 W.
An abrupt p-n junction has a doping concentration of 1015, 1016, or 1017 cm-3 on the lightly doped n-side and of 1019 cm-3 on the heavily doped p-side. Obtain series of curves of 1/C2 versus V, where V ranges from -4 to 0V in steps of 0.5V.
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
If the cost of heat rises by $200 per year (uniform gradient) after the next year and the owner plans to keep the present building for 15 more years, if the interest is 10% per year, what is the cost of heat without the installation
A room has four doors and four light switches (one by each door). Sketch a circuit that allows the four switches to control the light - each switch should be able to turn the light on if it is currently off, and off if it is currently on.
The voltage on a 40 µF capacitor is found to be 12(1 - e-8t) volts. Find the voltage at t = 0, and the voltage at t = 0.1 second. How much energy is stored on the capacitor as t approaches infinity
Three of the above single phase transformers are connected as a 3-phase transformer bank. The high voltage side of the transformer bank is connected in Y and the power is supplied to the transformer bank through a transmission line
In a MOS cascode amplifier, the cascode transistor is required to raise the output resistance by a factor of 40. (1) If the transistor is operated at Vov=0.2V, what must its VA be
if a balanced, three-phase, 15MW total load is fed by a 138Kv power line at a 0.85 lagging power factor, determine the following. (a) The line current (b) The value of the capacitor in uf per phase, is a wye-connected capacitor bank is used to cor..
