hello,everyone I'm studying the IEEE article "LINE SPECTRUM PAIR (LSP) AND SPEECH DATA COMPRESSION" by author FRANK K. SOONG and BIING-H WANG JUANG.they proved that the LSP is practical.but I doubt about the theory. LPC inverse filter A(Z)=1+a1*Z^(-1)+a2*Z^(-2)+...+am*Z^(-m) P(z)=A(z)+A(Z^(-1))*Z^(-m-1) Q(z)=A(z)-A(Z^(-1))*Z^(-m-1) they proved that P(z) and Q(z) only have zeros on the uni...
