simulink-using threshold

Hi,

I am trying to simulate a case in simulink where i need to set the output to 1 when the input is between two threshold levels, otherwise the output is 0. I tried to use relay block, but it incorporates hysteresis which i do not want. PLEASE GIVE ME A SOLUTION.

Is there any problem with using comparator block (<=, >=) along with switch block to implement the logic ?

The answer is in your question. Don't use Relay block but Threshold Block... Friendly.

hah hah, thanks a lot, but the threshold block that i know is wrap to zero, it provides only one threshold(when the input is above threshold output is zero), i need two threshold values. can you help please?

I did it before but I just don't remember.I need to check my old models on my own laptop tonight.

I hope you'll get a faster answer.

Try the Interval Test block.
