up or down counting based on input signal value

14 views (last 30 days)
I have to design a counter that counts up when the input signal value is 1 and the same counter should count down when the same input signal value is 3.
How do I do this in simulink??

This is one approach, the counter will increment at each sample time of the delay block (z^-1). You can set that parameter in the delay block dialog box

Request you to refer the attached image for the expected counter algorithm.

In your problem description you said you wanted the counter to count down when the input is 3 and countup when the input is 1, this is what the above model does. You also did not say anything about the counter resetting, which seems to now be indicated in your hand sketch. Please try to provide a more complete specification for what, exactly, you want the model to do. Maybe a little context for the application would be helpful too.
