An LRC circuit has L=0.1H, R=3Ω and C=(1/45)c. The circuit is subjected to an applied force of F(t)=-410*cos50t - 300*sin50t. q(0)=0 and q`(0)=0. Calculate the steady-state current for the cir
Assume the factory described in the previous problem is fed from a line having an impedance of 0.02 + j0.16 O. The voltage at the factory is maintained at 480 V(rms). Find the average power loss in
Using a 74LS169, 74LS47, and a Seven Segment Display, design a circuit using a binary counter that sequentially counts from 0 through 9 and displays the count on an LED. When the count reaches 9 the
Design the entire circuit implementing each of the three outputs with a two-level circuit plus inverters for the input variables. Begin the design with the following equations for each of the two bi
a 500-turn toroid of square cross section has an inner radius of 10cm and an outer radius of 15cm. The relative permeability of the core is 1000. For a current of 10A in the coil, calculate(a) the e
A sequential circuit with two D flip-flops, A and B; two inputs x and y; one output z; is specified by the following next-state and output equations: A(t 1) = x' y x A B(t 1) = x' B x A Z = B a) Dra
A T flip-flop has two operations: storing the previous value when T=0, toggling, i.e. complementing, its value when T=0. a) Tabulate the characteristic table b) Drive the characteristic equation. c) T
Consider an RLC circuit with a Vs (t)- voltage source. Let the values of the resistor, capacitor, and inductor be unity. Plot the poles and the zeros and the corresponding frequency responses of the
Use the even and odd decomposition of x h (t) to obtain its Fourier coefficients. This computation of the Fourier coefficients of x h (t) avoids some difficulties when you attempt to plot its magnit
desgin an 8-bit 2' complementer using sequentail circuit . you may use one register to store the data to be complemented, one register to store the complemented data, one half adder and one D-flip f
Sometimes the partial fraction expansion is not needed in finding the inverse Z-transform- instead the properties of the transform can be used. Consider the function F(z) = z+ 1/z^2(z - 1) a. Determ
Systems that operate under real time conditions need to be causal - that is, they can only process present and past inputs. When no real time processing is needed the system can be non-causal.
The input output relation of a non-linear system is y(t) = x2(t), where x(t) is the input and y(t) is the output. a. The signal x(t) is a band limited with a frequency max( max) = 2000*pi rad/sec. D
The Fourier transforms of odd and even functions are very important. The reason is that they are computationally simpler than the Fourier transform. Let x(t) = e-ItI and y(t) = e-tu(t) - etu(-t). a.
Three-phase transformers are grouped according to the phase shift between their primary and secondary phase voltages. Discuss the transformer classification adopted by the standards and elucidate th
