You use a shift register to store a value from one loop iteration to the next.

so if i have my output from the PMT connected to the DAQ box and using the DAQ icon in the block diagram as in the attacted file just apply a shift register is it...

I'm not very good at this and need it for the final year project.

Any other advice??

Thanks

You'll also need a Select function where you decide whether you want to put a new value in the shift register or continue to maintain the current value in the shift register.
