$2$ A low pass signal g$($t$)$ sampled at rate of fs $>2$B needs reconstruction.The sampling interval is $=1/$Fs$.$

a$)$ If the reconstruction pulse used P$($t$)=($t$/($ts$/2)-1/2)$pSpecify the equalizer filter E$($f$)$ to recover g$($t$).$

b$)$ If the reconstruction pulse used is P$($t$)=$ sin$(2$pit$/$T$)[$u$($t$)-$u$($t$-$Ts$/2)]$Specify the equalizer filter E$($f$)$ to recover g$($t$).$

c$)$ If the reconstruction pulse used is$)$delta$($t$/($Ts$/2)-1/2)$Specify the equalizer filter E$($f$)$ to recover g$($t$).$
