Description
On page 13 of the book, truly page 27 of the pdf, in Section 2.2.1 "The theory behind logic gates", you write:
"As logic gates implement Boolean functions, a set of Boolean functions is functionally complete, if this set can construct all other Boolean functions can be constructed from."
This, I think, is grammatically incorrect. I would suggest changing the ending of the sentence to:
"...is functionally complete if the set can construct all other Boolean functions."
You probably don't need the "," between 'complete' and 'if' it makes it appear as if it could follow directly after "As logic gates implement Boolean functions...", rather than signaling a pause or clause separation.
There are a few other grammatical errors in this section, along with incomplete sentences and unnecessary repetition.
