Find all real-valued filters of length 2, which satisfy only the Self- Orthonormality condition

Its just as the title states: Find all real-valued filters of length 2, which satisfy only the Self-Orthonormality condition



I'm quite stuck on this problem. We are working with OCQF filters right now
and I'm unsure how to generalize this for all filters of length two and make it specific to ONLY the Self-Orthonormality condition



More important than the answer, I would like to know how to approach this problem and problems like this
