How can I apply this transfer function to this signal?

Can't seem to figure it out

close all; clear all; clc;

fs = 36000;

ts = 1/fs;

%200 - 10000 hz

t = 0:ts:10;

y = chirp(t,200,10,10000);

fft_input = abs(fft(y,length(y))); % Converting signal into frequency domain

D = [1 0 -1]; % Numerator of Transfer Function

J = [1 -2 2]; % Denominator of Transfer Function

G = tf(D,J);  % (s^2-1)/(s^2-2*s+2) Transfer Function

OUT = G(fft_input); % Trying to apply transfer function to signal
