Design a full-adder using only a minimum number of 2x4 decoders. The complements of variables are not available but logic levels 1 and 0 are available.
A person with a receiver is 5 km away from the transmitter .What is the distance that this person must move further to detect a 3dB decrease in signal strength.
Using 4-bit numbers to save space, multiply 3ten x 4ten in binary.
Consider a step-down transformer with 15 turns in the primary and 6 turns in the secondary windings.Calculate the input impedance of this transformer loaded to an 8 O resistor, assuming that series resistances of the windings are negligible.
Efficiency in a power transformer is 98.6 percent when loaded such that its copper losses are five times its core losses. Calculate the per unit resistance of this transformer.
A tooling designer is designing a jig that will insert pins into the flip-up handles of a coffeemaker. The bin to hold the pins should hold enough pins for 3 hours' work before reloading. The engineering estimate for the rate of inserting the pins..
Solar Cell Consider a GaAs PN junction solar cell with the following parameters. Na=10^17 cm^-3, Nd= 2*10^16 cm^-3, Dn=190 cm^2/s, Dp=10 cm^2/s, Tn0=10^-7s, and Tp0=10^-8s.
How many turns are required for a circular loop of 100-mm radius to develop a peak emf of 10mV if the loop rotates 30r/s in the earth's magnetic field Take B = 60E-6T.
Explain why it is unlikely one would encounter a circuit exhibiting a critically damped response in practice. What impact would time and temperature have on a supposedly "critically damped" circuit
Mrs. Brooke owns a robot with an FSM brain. The robot walks from left to right along a paper type containing a sequence of 1's and 0's. On each clock cycle, the robot walks to the next bit.
1) When discussing the generation of electron/ hole pairs by light in semiconductors is it best to use the wave or particle rendition of light energy. 2) In what type of electron transition from valence to conduction band is momentum conserved, dir..
how do we determine the direction of current in a multiloop circuit with more than one source of e.m.f?
A shunt DC motor has RA = 0.7-ohm and VT =429.6 V. For an output power of 50.4 hp, we have nm = 1,452 rpm and IA = 110.8 A. The field current remains constant for all parts of this problem. Find the rotational power loss in watts.
