Which constraint exacerbates ISI’s effect during adaptive equalization?

A)Limited equalizer filter tap length
B)High signal amplitude stability
C)Excessive carrier frequency offset
D)Low channel signal-to-noise ratio

💡 Explanation

ISI increases with an inadequately sized filter, because limited coefficients impair channel estimation performed by the *adaptive equalization* process; therefore, uncorrected preceding symbols interfere, rather than being resolved without error propagation assuming convergence.
