The light sensor, which is active when it is dark, monitors the outdoor light and the timer can be programmed to any time. Design the logic to turn on an indoor light if it is dark outside and the timer has set the enable. A high turns on the ligh..
The core is made of cast steel. Find the MMF required to get an air gap flux of 60,000 lines. The cross sectional area of the center section and air gaps is 4 in^2. The remaining sections have a cross sectional of 6 in^2.
The treasure map in the figure gives the following directions to the buried treasure: "Start at the old oak tree, walk due north for 530 paces, then due east for 130 paces. Dig." But when you arrive, you find an angry dragon just north of the tree..
compute the diameter in centimeters of a steel rod an aluminum rod and a copper rod which can withstand a particular
Using the expression relating the rate at which current changes in an inductor to the voltage produced at it, find the voltage across the inductor when a switch supplying 7.9 A to a 2.4 mH inductor is suddenly opened.
A shunt dc motor has RA = 0.1-ohm and VT = 440 V. For an output power of 16.1 hp, nm = 1,213 rpm and IA = 103 A. The field current remains constant. Find the the rotational power loss in hp.
Find the maximum acceptable propagation loss for the system, given that the transmit power at the base station is 30W, base station feeder losses are 15 dB, the base station antenna gain is 6 dB, the mobile antenna gain is 0 dBi and the mobile fee..
A hollow spherical conducting shell of radius a has filamentary connections made at the top (r = a, θ =0) and bottom (r = a, θ = π). A direct current I flows down the upper filament, down the spherical surface, and out the lower filament.
A linear time-invariant continuous-time system responds to the following inputs with the corresponding outputs:Ifx(t) = u(t), then y(t) = 2(1- e^-t)u(t) and if x(t) = cost,then y(t) = 1.414 cos(t - pi/4).
1. What is a binary numbers?2. Explain the floating point representation? What is its utility? What is Excess-32 notation?
What happens to the propagation delay of the N-bit full adder as N is increases from 2 bits to 32 bits Compare and contrast this method of building an adder with the carry look ahead method described in your textbook
