Question

What has been modelled in the following Simulink screenshot?

(a) The step response of the unit step signal with a step time=0

(b) The step response of the ramp signal with a step time=4

(c) The ramp response of the step signal with a ramp slope=1

(d) The step response of the unit step signal with a step time=2

The question was asked by my college professor while I was bunking the class.

The above asked question is from Modeling in portion SIMULINK and GUIs of MATLAB

Answer 1

The correct answer is (a) The step response of the unit step signal with a step time=0

Easiest explanation: Since the step function is given as an input to the system whose transfer function is s, the above screenshot shows the modelling of a system whose impulse response is a step function while the input is also a step function. The graph suggests that step time is 0.
