Find a differential equation for the capacitor voltage,Vc(t) . Solve for this voltage by hand calculation. From this, find the solution to parts a) and b) in the problem. Then define state variables, determine the required initial conditions, and use Matlab to solve for voltages Vc(t) and Vo(t). Plot the results, and verify that the numerical solution using state variables matches the hand calculation solution.
a. What are the cyclic frequency (in Hz) and period of this signal b. Express this signal in the Quadrature and Sine/Angle forms. c. Express this signal in terms of complex exponentials (hint - use Euler's identity equation).
Suppose the FCC allocates 300 kHz channels for a high quality video conference service. A service provider decides that this service requires 720 kbps (not including overhead and error control) for each channel.
Measurements taken on various resistors are shown below. For each, calculate the power dissipated in the resistor and the power rating necessary for safe operation using standard components with power ratings of 1/8 W, 1/4 W, 1/2 W, 1 W, or 2 W
