← ScienceWhich effect occurs because RF filter bandwidth narrows?
A)Increased inter-symbol interference✓
B)Reduced signal group delay
C)Improved adjacent channel rejection
D)Decreased required carrier power
💡 Explanation
Excessive filtering limits frequency components, therefore increased inter-symbol interference occurs. This is caused by pulse dispersion from bandwidth narrowing rather than improving rejection, because delay decreases influence on data integrity less.
