No IF vs Low IF - when, why, and how?

Postby Jrodh13 » Sun Apr 16, 2017 10:05 pm

I'm trying to understand the differences between No IF and Low IF and how they relate to a regular Intermediate Frequency for analog receivers.

Anyone have any good way of explaining it or any good books that explain it in simple terms?

I'd also like to learn when an why one or the other is used.


Thanks,
Jared

This question gets asked often and there are a lot of discussions on the net, just google it. Here is one thread that describes some of the trade-offs in simple terms...

I did some google searches, but often find them rather complicated and confusing. I'll take a lot at this link.

Any other suggestions are welcome.


Thanks,
Jared
