The following binary numbers have a sign in the leftmost positionand, if negative, are in 2s complement form. Perform the indicated arithmetic operations and verify the answers.
a.) 110001 - 010010
b.) 101110 - 110111
The op-amp circuit measures the changes of temperature in a system. The output voltage is given by v0(t) = -R(t)vi(t). Suppose that the temperature in the system changes cyclically after t = 0, so that R(t) = [1 +0.5 cos(20πt)] u(t) and let the in..
Consider an open-ended cylindrical tube (infinitesimally thin walls) of radius a and total length 2h. A total charge Q is uniformly distributed over the surface of the tube. Find an expression for the electric field anywhere on the axis of the tub..
design a 4 bit register with 4 different kinds of flip flops, that has at least 12 different functions. list clearly the functions. Do something creative, and say exactly your innovation. at least one flip flop should have some input besides a mul..
If the per-phase line loss in a 60-km-long transmission line is not to exceed 60kW while it is delivering 100A per phase, compute the required conductor diameter, if the resistivity of the conductor material is 1.72*10^-8 Ohm-meters.
Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 12mA. The zener has an incremental resistance r(z) = 30 ohms and a knee current of 0.5mA. The regulator operates from a 10-V supply and has a 1.2k-ohm load.
what is context based arithmetic coding?and it is calculated .
A load consists of a resistance R in parallel with a capacitor of reactance X. The load is fed from a single phase supply through a line of impedance 8.4 + j11.2 ohms. The rms voltage at the load terminal is 1200 at 0 degress V rms,
Sketch the appropriate equivalent circuit and phaser diagram and, assuming step-down operation, determine (a) the magnetizing current and the core-loss component of exciting current; (b) the exciting current; (c) the no-load power factor; (d) the ..
A parking garage charges a $ 5.00 minimum fee to park for up to three hours and an additional $ 1.00 per hour for each hour over the hours. the maximum charge for any given 24 hours period is $ 2.00.
The propagation law follows the free space up to a distance ofdbreak = 50 meters, and for larger distances the receive power is similar to(d/dbreak)-4.2. Transmit antenna gain is -7dB; the receive antenna gain is 9 dB. Compute the available fadi..
Write the switching expression for the burglar alarm that produces a logic 1 (rings a bell) when the safe is moved and the control switch is closed, or when the closet is o pen after banking hours, or when the closet is opened with the control swi..
A 20-MVA, 12.2 kV, 0.8-PF lagging , Y connected synchronous generator has a negligible resistance and syncronous reactance of 1.1 per unit. The generator is connected in parallel with a 60-Hz, 12.2-kV infinite bus that is capable of supplying or c..
