a 3 V voltage generator is depicted as a thevenin model, the impedence of the generator is represented by a parallel resistor-capacitor combination, the value of the resistor is 20 ohms and the value of the capacitor is 10 farad.
An industrial load consumes 88 kW at a power factor of 0.707 lagging from a 480 Vrms line. The transmission line resistance (Rline) from the power company's transformer to the plant is 0.08 Ohms.
When the input x(t) = 5u(t) is applied to a linear second-order circuit the response of the state variable is y(t) = 10e^(-100t)-5e^(-200t) + 5. Design a simple RLC circuit that would produce all of these responses.
Recall that for discrete sequences the ts sample period (the time period between samples) is the reciprocal of the sample frequency fs. Write the equations, describing time-domain sequences for unity-amplitude cosine waves
