However, lsim discretizes the continuous-time LTI system and then propagates the approximate solution in discrete-time. In that case, the value of the input signal at t = 0 makes a difference. Consider, for example, what happens when lsim uses the zoh approximation (it doesn't always do this), where the discrete-time propagation reflects an assumption that the input is …Back in the old days, transferring money to friends and family was accomplished by writing checks. This ancient form of payment was often made even more arduous by the necessity of sending the check via snail mail.The TransferFunction class can be instantiated with 1 or 2 arguments.
