Question

What does the following block do?

(a) Converts a Simulink signal to a physical Signal

(b) Converts a Simulink variable to a physical variable

(c) Converts a Simulink operation to a physical operation

(d) Does nothing

I got this question by my school principal while I was bunking the class.

This interesting question is from Simulation in chapter SIMULINK and GUIs of MATLAB

Answer 1

Right answer is (a) Converts a Simulink signal to a physical Signal

To elaborate: The above shown block does the work which converts a simulink signal to a physical signal. This is used to convert a signal from a transfer function toolbox, say, to a physical real signal which can be used for evaluation in circuits.
