11–30 The step response of a linear circuit is g t ð Þ=0:5 1 −e−250 t  

u t ð Þ. Find the output waveform when the input is v1ðtÞ = 20 e−200t  

u t ð Þ. Use MATLAB to find the Laplace transforms of gðtÞ and v1ðtÞ. Then find V2ðsÞ. Finally, use the inverse Laplace function to find the waveform v2ðtÞ and plot the results.
