The coherent detector for the demodulation of DSB-SC fails to operate satisfactorily if the modulator experiences spectral overlap, explain the reason for this failure.
Design a 4-bit register with 2 control inputs s1 and s0; 4data inputs I3,I2,I1 and I0; and 4 data outputs Q3,Q2,Q1 and Q1. When s1s0=00, the register maintain its value. When s1s0=01, the register loads I3...I0. When s1s0=10, the register clears i..
Consider a 32-bit data bus in a chip. Assume each bit has P0 = 0.2 and P1 = 1 P0 = 0.8 and all the 32 bits are statistically independent from each other. Estimate the power saving when we use the bit-invert technique.
Two inductors with two separate cores are used in parallel in a circuit to share the current. A customer request a design improve by putting the two windings on to the same core. 1. Draw the two windings and resulting magnetic field; 2. If 10 turns..
Design the system which finds the most popular (one most often generated) symbol called winner in each block of 32 input symbols. The system reports the number of winners and their value. Use only 2 data inputs multiplexers and shift registers.
Design a BP filter using two-integrator topology. The center frequency is to be 10kHz with a bandwidth of 2kHz. Design to obtain a voltage gain of 26dB.
David has a collection of resistors of various values, but all are rated for the same power capacity of 2 watts. Show how he can combine resistors to obtain an effective resistance of 50 ohms rated for 10 watts.
The solution of any differential equation is composed of the sum ofa transient solution and a steady state solution. What are the general mathematical properties of the transient solution
A synchronous generator rated 1350 MVA at 0.9 pf, 22.5-kV, Xs=11.6% is connected to a power system through a 1500 MVA, 7.9% 24-kV/230-kV generator step up transformer. The power is generated into a 230-kV system.
Determine the Laplace transform of the above signals (use properties of the Laplace transform) including the corresponding region of convergence.
The induced emf in a PMmachine is 400V at 1600rpm. What is the induced emf if the speed is changed to A.)800rpm B.) 1200rpm c.) 2000rpm
Determine the position x and the tension in the cord that is required for equilibrium. The cord passes through the smooth ring at B and has an unstretched length of 6ft and stiffness of k = 50lb/ft.
The donor ground states for tellurium in GaAs are 5.9 meV below conduction band (there are 2 of them because of spin). Atroom temperature (300 K), what is probability that a given ground state is occupied if the Fermi level (Ef) is 0.1 eV below Ec
