Consider a finite state machine that generates z = 1 when the previous four values of input variable 'w' are either '1001' or '1101'. Solve this problem by Mealy and by Moore. Show the state diagrams and the state tables.
A twelve pole, 480V, 60Hz synchronous motor has a reactance of 5 ohm. The field current is adjusted so that the equivalent field voltage Ef is 520V (line-to-line). Calculate the following: (a) Maximum torque. (b) Power factor at the maximum torque..
Express the field D = ( x + y ) ( x + y ) a)in cylindrical components and cylindrical variables b) Evaluate D at the point where = 2 , = 0.2 , and z = 5, expressing the result in cylindrical and rectangular components.
The DC resistance of the primary windings of a certain transformer is found to be 22ohm while the resistance of the secondary windings is 0.8ohm. When a 60 Hz sinusoidal source is connected to the primary "with the secondary open circuited"
Design an integrator whose output voltage Vo(t) is related to the input voltage Vin(t) by Determine the rate of integrator drift with Vin = 0 if the input-offset voltage VOS is 2mV
Hand calculate the expression for the voltage and current of the capacitor and plot these equations by using MATLAB and calculate the time constants of each circuit and point out this time constants at your voltage graphs.
The serial adder uses two four-bit registers. Register A holds thebinary number 1101 and Register B holds 1010. The carryflip-flop is initially reset to 0. List the binary values inRegister A and the carry flip-flop after each of of the fourshifts..
Design a low pass FIR filter for 10 kHz sampling, with a pass band edge at 2 kHz, a stop band edge at 3 kHz, and 20 dB stop band attenuation. Find the impulse response and the difference equation for the filter.
Consider a continuous-time LTI system with frequency response of H(j omega) = 1 + j 250 omega/(2 - j 50 omega)2 Find the expression for the magnitude of H(j omega) and sketch its Bode plot (sketch asymptotes and the magnitude curves).
