What is the limiting condition for sensitivity in a communications receiver?
The noise floor of the receiver.
What is the definition of the term “receiver desensitizing”?
A reduction in receiver sensitivity because of a strong signal on a nearby frequency.
What is the term used to refer to a reduction in receiver sensitivity caused by unwanted high-level adjacent channel signals?
Desensitizing
