Python Assignment:

The goal of this problem is to write a function, step_current, that returns a current with amplitude I), given time ( t ). The function will have 3 inputs: t, t_step, I_step and 1 output: I. The function should operate for 4 different input parameter settings: a. I = step_current (t) Given no amplitude parameters, the function should return a current following the unit step function u(t). That is, I(t)=0,0.5,1,t0 b. I = step_current (t,t _step ) Again, no amplitude is provided. If t_step is a scalar, I should follow the function u(t-t_step). That is, I(t)=0,0.5,1,ttstep If t step is a vector {tk}, return a 0 if t length(t_step), ignore elements of I_step greater than length(t_step). If length(I_step)
