Question

What does this block do?

(a) Gives a logic 1 if the input is greater than it’s previous value

(b) Gives a logic 0 if the input is greater than it’s previous value

(c) Gives a logic 1 if the input is smaller than it’s previous value

(d) Gives a logic 0 if the output is greater than it’s previous value

This question was posed to me by my college professor while I was bunking the class.

This key question is from Modeling in section SIMULINK and GUIs of MATLAB

Answer 1

The correct choice is (a) Gives a logic 1 if the input is greater than it’s previous value

The best explanation: The above block gives a 1 if the input is strictly greater than it’s previous value. It returns a 0 if the input is less than or equal to it’s previous value, as defined in SIMULINK TOOLBOX.
