Receiver sensitivity will depend on RF bandwidth or IF bandwidth.?

Question

I have three receivers one is superhetrodyne receiver, second receiver is one whcih dont have any down conversion and thrd receiver is Zero IF receiver.can anyone help me to calculate the sensitivity of the above three receivers.

Answer 1

I don't think you are using the word 'sensitivity' quite the way you think you are.

Bandwidth is kind of weird to use as a direct reference to sensitivity. They are related in the equation, and both RF and IF bandwidth make a difference.

There is an excellent reference on wiki at http://en.wikipedia.org/wiki/Sensitivity...
