hi everybody, i need help to plot the frequency response of the transfer function give below
s(w)=(1+exp(-1j*w)); x(w)=(a0*exp(-1j*6*w)+a1*(exp(-1j*4*w)-exp(-1j*8*w))+a2*(exp(-1j*2*w)-exp(-1j*10*w))+a3*(1-exp(-1j*12*w))); y(w)=(a0*exp(-1j*6*w)-a1*(exp(-1j*4*w)-exp(-1j*8*w))-a2*(exp(-1j*2*w)-exp(-1j*10*w))-a3*(1-exp(-1j*12*w)))*exp(-1j*w);
z(w)=s(w)*(x(w)+y(w));
in this equation i have replaced z^-1 by exp(-jw); a0,a1,a2,a3 are filter co-efficents; a0=h1+h3+h5+h7 a1=h3+h5+h7 a2=h5+h7 a3=h7 and conditon is h0=2(h1+h3+h7....)
