Which consequence results when the LED within an optocoupler degrades from excessive reverse voltage?

💡 Explanation

Signal distortion results because *photon flux reduction* within the LED leads to inconsistent transistor behavior. Therefore, the optocoupler’s output becomes unreliable, rather than showing improved CTR or noise immunity under these conditions.
