  6. Apply the Laplace transform operator to generic waveforms and calculate the inverse Laplace transform of a given s-domain function
  7. Solve for currents and voltages in generic RLC circuits
  8. Model RLC circuits with transfer functions.
  9. Calculate the output waveform from an input waveform and a system’s transfer function
