2 coils are magnetically coupled. There are 2 possibleconductance values when the coils are in series: 25 H and 23H. Calculate the value of coupling coefficient, K
Derive the three-term error correction formula. Include the appropriate signal flow graphs in all of your derivations. Hint: The one-term and both two-term error models are simplifications of the threeterm error model.
A function f has four inputs a,b,c,d and one output such that the output is a 1 if and only if the number of 1s in the inputs is even. (a) Derive the truth table for f. (b) Write the canonical sum-of-products expression for f.
Although sums behave like integrals, because of the discrete nature of the sums one needs to be careful with the upper and lower limits more than in the integral. To illustrate this, consider the separation of an integral into two integrals.
The electric field in a region of space is E= 4 ax V/m and the magnetic flux density is B= 5 az Wb/m2. At t= 0 a particle with mass 1 kg and charge 1 C is located at the origin traveling at a velocity of u0= 10 ay m/s.
A 60 Hz, three-phase, transposed transmission line has the following parameters: Z = 13.114+ j52.952, Y = j0.311/1000. The sending-end line-to-line voltage is 161 kV. The total receiving-end load is represented by ZL =143 with an angle
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..
Calculate in polar form the sequence components of unbalanced lineto-neutral voltages and calculate in polar form the phase currents corresponding to the sequence components
aluminum has the FCC crystal structure. Its atomic weight is 26.98g/mole, and its density is 2.70g/cm3. Determine the atomic radius of a single aluminum atom.
An early code used in radio transmission involved using codewords that consist of binary bits and contain the same number of 1s. Thus, the 2-out-of-5 code only transmits blocks of 5 bits in which 2 bits are 1 and the others 0.
A Si bar is 0.25 cm long and 500 ?m2 in cross-sectional area. It is grounded at x=0 and biased at +20V at x=0.25 cm. Find the resistance and the current at 300K (a) when the Si bar is doped with 2×1017 cm-3 arsenic
Each of these bands is split into two, allowing two operators. An operator is allocated 12.5 MHz in each direction. Each channel is allocated 30 kHz. If 21 channels are allocated for control, what is the total number of voice calls per operator.
a) Show how to implement a 4-to-1 multiplexer with an active high output and no enable using two of the 2-to-1 MUXes and a minimum number of additional gates. b) Repeat part (a) for a 4-to-1 multiplexer with an active low output.
