Which of the following describes problems caused by poor dynamic range in a receiver?
Spurious signals caused by cross modulation and desensitization from strong adjacent signals✓الإجابة الصحيحة
Oscillator instability requiring frequent retuning and loss of ability to recover the opposite sideband
Poor weak signal reception caused by insufficient local oscillator injection
Oscillator instability and severe audio distortion of all but the strongest received signals
الشرح
Dynamic range spans the weakest signal a receiver can detect and the strongest it can handle while still behaving linearly. When that span is too small, strong adjacent signals drive the front end into nonlinearity, producing cross modulation and spurious products and reducing gain for the wanted signal; oscillator instability and injection level are separate faults.
