A Design Method for High-Audio-Quality FM Multiplex Encoders
FM multiplex encoder design has up to recently relied on either the analog multiplier (matrix) technique or the switching method. Both suffer from significant audio performance drawbacks. Recently some attempts were made to use digital sampling in order to solve these problems. An alternative digital sampling method is presented, which closely emulates the operation of an ideal multiplier. An extension of this technique to decoder design is also considered.
