Design an excess-2 code converter to drive a seven-segmentindicator . the four inputs to the conducter circuit is (A,B,C, andd) represent it in Excess-2 code decimal digit. the inputs aredigits 0-9, so the six unused combinations are dont cares. so design your circuit using only two-, three-,and four-inputs NANDgates and inverters. try to minimize the number of gates andinverters . (A,b,c,d ) will be availble from the toggleswitches . any solution with 17 or fewer gates and inverters( not counting the four inverters for the inputs) is acceptable.
A separately excited DC motor runs at1500 rpm under no load with 200 V applied to the armature.The field voltage is maintain at its rated value. The speed of the motor, when it delivers a torque of 5 Nm ,is 1400 rpm.
A 1-uF capacitance is in parallel with the series combination of a 6-uF capacitance and a 3-uF capacitance. Sketch the circuit diagram and determine the equivalent capacitance of the combination.
Determine the current drawn from a three-phase 440 V line by a three-phase 15-hp motor operating at full load, 90% efficiency, and 80% power-factor lagging. Find the values of P and Q drawn from the line. (Hint: 1hp = 746W)
Design a system that repeatedly computes and outputs the sum of all positive numbers within a 512 word register file A consisting of 32-bit signed numbers.
A PN flip-flop has four operations, clear to 0, no change,complement, and set to 1, when inputs P and N are 00, 01, 10, and11, respectively. (a) Tabulate the characteristic table. (b) Derive the characteristic equation.
find the complete functions, p(t) and w(t) supplied by the element, not just a number, and graph p(t) and w(t). Choose appropriate intervals of time for your graphs. Assume that both v(t) and i(t) are zero for t
A 220 V shunt motor has armature and field resistance of 0.2-ohm and 220-ohm respectively. The motor is driving a constant load torque and running at 1000 rpm drawing 10 A current from the supply.
In a circus act, a performer (m = 93kg) stands on a spring (k = 9500 N/m) that is compressed by 1.2 m. The spring is released and the performer launched in the air. Ignore air resistance. A) How high does the performer reach above where the spring ..
Design your circuit so that the STOP push button must be pressed before the motor can be switched direction Also incorporated a 5 second delay to inhibit restart after the STOP push button has been pressed Green light
Find the complex impedance of the inductance. Find the phasor voltage and current, and construct a phasor diagram. Write the current as a function of time. Sketch the voltage and current to scale versus time. State the phase relationship between t..
On the other hand, when S is high,we should have O1 = I2 and O2 =I1. Thus, S acts as the control input for a reversingswitch. Use Karnaugh maps to obtain a minimal SOP(sum ofproduct) design. Draw the circuit.
Consider the current it takes to power a +5V 74xx245(Icc). What is the qualitative difference between the CMOS devices and the non-CMOS devices and the non-CMOS devices What is the explanation for the difference
