In this problem, we explore an equalization method used to avoid intersymbol interference caused in PAM systems by the channel having nonlinear phase over its bandwidth.

When a PAM pulse with zero-crossings at integer multiples of the symbol spacing is passed through a channel with nonlinear phase, the received. Pulse may no longer have zero-crossings at times that are integer multiples of . The order to avoid intersymbol interference, the received pulse is passed through, forcing equalizer; which forces the pulse to have zero-crossings at integer multiples of . This equalizer generates a new pulse y(t) by summing up weighted and shifted versions of the received pulse x(t), The pulse y(t) is given by
