I have some problems with FIR filter,someone can help me?

I write my pseudo code:

clear all;
Asim=[17, 18]; %Definisce le ampiezze
Tsim=[22.5, 33.48]; %Definisce i periodi
fase=[1.1, 2.2]; %Definisce le fasi
p=1:2048;
value=0; %Oscilla attorno la linea dello zero se value=0
Coseno1=0;
Coseno2=0;
Coseno1=Coseno1+Asim(1)*cos(2*pi*1/Tsim(1)*p+fase(1))';
Coseno2=Coseno2+Asim(2)*cos(2*pi*1/Tsim(2)*p+fase(2))';

serie12=Coseno1+Coseno2;
step =0.01;


serie= serie12;
step=0.01;
Tmin=8;
Tmax=120;
A=length(serie);

Y=fourier(serie',Tmax,Tmin,step); %fourier trasform



Ok , now how can I implement a high pass filter FIR, for cut off the frequency 1/ 33.48 ?
