Explanation: Dynamic range describes the ratio between the strongest signal a receiver can process without overloading or producing significant distortion (the largest tolerable input signal) and the weakest signal it can reliably detect above its internal noise (the minimum discernible signal). A wide dynamic range is crucial for a receiver to operate effectively in environments with both very strong local signals and very weak distant signals. Intermodulation distortion (A) is a type of spurious signal generation caused by strong signals mixing non-linearly, not the range itself. Noise floor (B) refers to the inherent noise level within a receiver, representing the lower limit of detection, but not the entire range. Noise figure (C) quantifies how much an active circuit degrades the signal-to-noise ratio, affecting receiver sensitivity, but it's not the overall operating range.
