Which side effect occurs when filter coefficient quantization becomes excessive in a digital hearing aid's signal processing?

💡 Explanation

Excessive quantization introduces nonlinearities altering filter characteristics, leading to the risk of feedback oscillation because quantization noise increases the loop gain in the feedback path, therefore the hearing aid becomes unstable, generating unwanted oscillations, rather than behaving linearly in amplifying sound.
