hi, i have two input signals which are either 1 or 0.
Input 1 is always high and input 2 is high too, but input 2 periodicly goes very shortly from 1 to 0. Each time wenn input 2 goes from 1 to 0, output changes its state and it will keep the state until the next change from input 2(1 to 0) come.

how can i achieve this? i have been trying to mess with an
SR flip flop but i am not sure how to configure it.

thanks for any help (i need it!)

Use a J-K Flip-Flop, connect clk to input2 and both J and K to constant 1. This should do the job.
