For a RC circuit, we can use Laplace transforms to show that when we apply a step input of 5V, the voltage across the capacitor rises exponentially to a final value equal to step input. Now, suppose that an initial voltage of 1V is present at the capacitor at zero time (t = 0). Will the behavior of the circuit when a step input is applied still yield an exponential rise or will the behavior be of some other type? Prove by solving the equations using Laplace transform.
Derive the state space quation of a DC motor with supply voltage and load torque as inputs and armature current, angular speed as outputs.
By reference to the equivalent circuit explain why the device is a pass-band filter and suggest a design modification which would more closely define the band, and why.
An input signal of 10V at 0degrees and a frequency of 1592Hz is applied to a series RLC circuit with resistor R=100ohm, inductor L= 40mH, and a capacitor C=0.5uF. The value of the total circuit complex impedance is
In this problem you will design a Moore finite state machine that realizes a synchronous 3-bit counter with a mode control input M and three outputs QA, QB, and Qc. When M = 0, the counter output advances through the 3-bit numbers using a step si..
