2) What is the fundamental difference between a continuous signal and a discrete signal?
3) Why are linear time invariant (LTI) systems so important in engineering and engineering analysis?
4)When solving a second-order differential equation of the form shown below, what effect can changing the coefficients a, b, and c have on the waveform of the solution of the differential equation (i.e., waveform of i as a function of time)?
