I'm a physics major (undergrad) who wants to learn real and complex analysis, but don't have the time to do the courses in my programme. Can anyone recommend a good textbook for learning the subjects on your own?
I need to be able to receive two AM radio stations. I haven't figured out what values I need yet. I'm just looking for different suggestions about how to construct one.
Edit: Maybe something around the 100 pf range.
I have to make a homemade AM radio receiver for a physics course I'm doing, and I'm looking for any suggestions on the best way to make a homemade variable capacitor. I'm not expecting anyone to do my work for me of course, but any suggestions that anyone could offer would be appreciated.
