A short coursework item involving the design, build, testing and evaluation of a fourth-order low pass filter of IGMF topology, having a maximally flat response with a cut-off frequency of 60Hz and a pass-band gain of 5.
I have been told this sentence is grammatically incorrect. I said, that to my knowledge, I don't think it is. It is, however, a little bit lengthy and could probably be made much more readable if the sentence was broken up.
The person that initially informed me that it's grammatically incorrect is Chinese, so I assume that their grasp of grammar is based off rules, rather than intuition (like mine).
I asked another person and they have told me that it lacks an 'active verb' - I've done some research on this, and I don't think this is the problem.
How exactly would I modify the sentence to make it grammatically correct, if it isn't?
In response to Canis:
Can you point out the subject, verb, and object, along with any modifiers? Specifically, what do you think is the verb, and why? If you put your reply into an edit of your question, it will be read by more people. – Canis Lupus
