Stereo Encoder for FM broadcasting. High quality stereo coder.
"This stereo encoder is a halfway between analogue and digital processing. It combines the best from both domains to provide high-quality and easy to build device. 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 micro controller allows to build this stereo encoder with reduced part count and get excellent results in real operation."
Characteristics:
- Signal overshooting prevention (overshooting max. 10 %)
- Low noise and distortion
- Pilot tone level, audio gain and output level adjustment
- High channel separation and spectral purity in common operation
- RDS input and pilot sync. output makes easy to connect any RDS encoder
- Microcomputer controlled
