This paper presents a microcontroller based digital encoder capable to generate baseband signals using different types of line codes. The baseband coding is an essential processing found in a very wide range of industrial data transmission systems, wireless and optical communications and also in computer networks. The proposed system has the capability to operate with an extended range of unipolar, bipolar and multilevel codes. In addition to data transmission, the presented design can also be used in analysis and experimental study of nonstandard encoding schemes as well as for didactical purposes. The hardware structure of the system is based mainly on PIC18F4580 microcontroller. Codes requiring bipolar and multilevel operation are implemented using dedicated converters connected to the output ports of the microcontroller. The data source for the encoding system can be internal or external, being selectable by the user. The relevant parameters regarding the system operation are continuously presented on a local LCD. Compared to other similar structures, the system provides a compact and reliable implementation, based on a high-performance microcontroller, and offers an extended versatility in the selection of the coding schemes.
