Here’s a high quality stereo encoder using PIC18F1220 microcontroller. The sampling frequency used in this stereo encoder is 97 times higher than the pilot tone frequency . This makes very easy to reject all spectral residues around the sampling frequency without affecting the main signal characteristics. Using of a microcontroller allows to build this stereo encoder with reduced part count and get excellent results in real operation. Here’s a stereo encoder block diagram: This stereo...
