Practical exercises with LTSpice
Exercises description
Simulate the time characteristics k(t) of the systems (from the figure below) with impulse excitation and unit step excitation:
Assume the following element parameters:
a) and b) L=249.6 mH, \( r = 5.02\Omega \), C = 470 nF, \( R=150\Omega \)
c) L=249.6mH, \( r = 5.02\Omega \), C = 470nF, \( R=2k\Omega \)
d) L=249.6mH, \( r = 5.02\Omega \), C = 470nF, \( R=1k\Omega \)
Determine the frequency characteristics of the tested two-port devices.
Using the transfer function and the inverse Laplace transform, analytically determine responses of the systems and compare them with the simulated ones (impulse excitation (Dirac delta) and unit step function (Heaviside)).
When you're done, compare the result with the video for one case:
