What is the term used for the decibel difference (or ratio) between the largest tolerable receiver input signal (without causing audible distortion products) and the minimum discernible signal (sensitivity)?

Dynamic range is the measure of a receiver's ability to handle a wide range of signal strengths. It is defined as the decibel difference between the strongest signal the receiver can handle without producing audible distortion and the weakest signal it can detect above the noise floor (its sensitivity). If a receiver has poor dynamic range, strong nearby signals will overload it and create distortion products that mask weaker signals. A high dynamic range ensures that you can still hear faint stations even when very strong stations are transmitting on nearby frequencies. Distractors like 'noise figure' refer only to the internal noise added by the receiver, while 'stability' refers to the receiver's ability to stay on a specific frequency without drifting. Dynamic range uniquely spans both the upper limit of overload and the lower limit of sensitivity.
