Extra exam question E7E09

WhySpurious mixer products are generated when input signal levels to a mixer are too high. When input signal levels to a mixer are too high, the mixer is driven outside its intended linear operating range and generates spurious mixer products, unwanted extra frequencies from nonlinear mixing that weren't part of the desired sum/difference output, answer A. "Mixer blanking" and "automatic limiting" aren't standard mixer effects, and excessive AGC voltage is a receiver-level symptom elsewhere in the signal chain, not a description of what happens inside an overdriven mixer itself.
