The voltages at opposite ends of a 470Ω, ±5% resistor are measured as V1 = 12V and V2 = 5V. The measuring accuracy are ±0.5V for V1 and ±2% for V2. Calculate the current in the resistor and specify its accuracy.
a three phase 25 kva 208 V 60hz alternator operating under balancedsteady state conditions , supplies a line current of 20 A per phaseat a 0.8 lagging power factor and a rated voltage. determine the power triangle for this opertaing voltage.
A 4-bit adder will be used to add a 3-bit unsigned number (0-7) and a 2-bit unsigned number (0-3), producing a 4-bit result. Design a combinational circuit with a complete truth table, K-maps and circuit diagrams using multiplexers and discrete lo..
If a RAM memory has a 5-to-32 row address decoder and a 6-to-64 column address decoder, and eight pins I/O, what is the size of the memory
For a RLC Circuit: V=110V (rms) at 50Hz; R=5 ohms; L=50mH; C=0.1 mF; find the impedance, current, voltage across R parallel to C, peak electric energy, peak magnetic energy and stored energy.
The output power of the digital transmitter is 0 dBm and the link has a constant attenuation of 50.0 dB. At the input to the receiver, the equivalent AWGN noise power is – 70 dBm. Assume implementation margin is 0 dB when calculating BER 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..
An electronic circuit board with lambda(t) = 0.00021 h^-1 is replaced on failure. What is the probability that the third failure will occur by 10000h ( hint: if there were 4 0r more failures by 10000h, that also means there were 3 failures by 1000..
Realize the function f(a,b,c,d,e) = Σm(6,7,9,11,12,13,16,17,18,20,21,23,25,28) using a 16-to-1 MUX with control inputs b,c,d, and e. Each data input should be 0,1,a, or a'. Hint: Start with a minterm expansion of F and combine minterms to elimina..
Show that a Johnson counter with n flip-flops produces a sequence of 2n states. List the 10 states produced with five flip-flops and the boolean terms of each of the 10 AND gate outputs.
The system receives three binary streams: A, B, and C. The system takes a look during each clock cycle at the last four bits of each stream (a(t), a(t-1), a(t-2), a(t-3)), (b(t), b(t-1), b(t-2), b(t-3)) and (c(t), c(t-1), c(t-2), c(t-3)).
The locked rotor current and locked rotor torque at a rated voltage and rated frequency are 725A and 120 percent rated torque,respectivtively. Determine a) rated line current b)rated torque c) minimum voltage required to obtain a blocked- rotor tor..
Assume all your standard value resistors are accurate to 0.1%. What would be the worst-case variation in overall resistance for your design (both high and low). How might you construct a resistive network using the smallest number of standard resis..
