Which risk increases when transmitted signal bandwidth approaches the Nyquist limit in digital communication?

💡 Explanation

Approaching the Nyquist limit heightens the risk of intersymbol interference because the limited bandwidth increases signal distortion so that symbols overlap. Therefore, adjacent symbols interfere destructively, rather than power or noise increases, under ideal noise conditions without excessive amplification.
