CORR=(X(:,1)-mean(X(:,1)))/g; %Shift of signal to zero value
%Plot Corrected signal in Time Domain
figure(3)
plot(t,CORR);
title('Corrected signal in Time Domain');
xlabel('Time [s]');
ylabel('Acceleration [cm/s^2]');

Can you attach the excel sheet 'sujith.xlsx' along with your entire code so we can understand better ?

Hi
I think it's just because there is an error in your code :
xdft=fft(t,CORR);
to be replaced by
xdft=fft(CORR,N);
