I want to know the answer to the following question:
Bell sketched a design that looked like the work of who?
All the background I'm provided with is that "Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" [N 16]". Is that enough to answer the question?
Answer: no
