This will probably take someone with hands on signal experience but here goes.Weve established I have a complmentary or differential  quadrature signal.I.E. +-a,+-b, index. Can this signal be split using only +A,+B ,index and disregard the rest.Im wondering If I can close to mach and galil . or is an useless effort.It may be usefull to others in any case. thanks Al
