The voltage across an element is 12e to the power of -2t . The current entering the positive terminal of the element is 2e to thepower of -2t .Find the energy absorbed by the element in 1.5 s starting from t=0
To develop contoller as a sequential circuit using minimum number of D flip-flops and the minimum number of external gates. the controller should set the values of the control lines appropriately to drive the combinational logic circuit.
The armature of a simple DC generator is rotating at a speed of 188.5 rad/s. If the armature consists of 3 turns per coil, and a current is flowing in the field coils such that the field coils produce a flux of 0.0333 Wb
Use a 74LS283N Adder chip and a 74LS86N XOR chip. Simulate the circuit in Multisim and test enough input combinations that you are sure the circuit is working properly. Make sure you test in all theranges of numbers that are possible.
A small circular parabolic reflector, often referred to as dish, is now being advertised as a TV antenna for direct broadcast. Assuming the diameter of the antenna is 1 meter, the frequency of operation is 3 GHz, and its aperture efficiency is 68%
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.
Assume that three non-negative integers are stored in memory locations M[$00], M[$01], and M[$02]. Write an assembly language program (with lots of comments) that will determine the largest of the three stored values and store the value in M[$03]..
Design a PLC program and prepare a typical I/O connection diagram and ladder logic program for the following motor control specifications:1) A motor must be started and stopped from any one of three start/stop pushbotton stations.
The following signals are sampled using a train of impulses with periodicity kT: signal x(t) Is sampled to obtain and signal y(t) Is sampled to obtain yc(t) Determine the range of values for T that allows complete recovery of x(t) from xc(t)
