What should be the conclusion?

Question

IT education

Good day to all. Straight to the point.
We have a teacher who requires writing non-stating conclusions on the work done (laboratory work, term paper, etc.)
I still can’t figure out how to write a non-stating conclusion.
Let's say we studied the work of detectors for AM, FM and FM signals.
A conclusion based on the obtained graphs of input and output signals is not suitable. The conclusion is that when changing something in the scheme, the graph will take such and such a form - too.
The teacher, however, still accepts papers with such conclusions, but always expresses his dissatisfaction with them.
So what to write? :)

Answer 1

If takes l.r. since you write, do not worry. The fact that he expresses his dissatisfaction there is another question, the main thing is that he does not underestimate the assessment.
