The purpose of this study was to determine the language use in media discourse in the Nḓevhetsini Programme on Phalaphala FM, to investigate linguistic elements that create challenges amongst presenters, reporters, listeners and guest speakers and also the manner in which the message is received by listeners. This study employed a qualitative approach to obtain data from Nḓevhetsini episodes. The episodes were divided into themes identified in order to compare common cases and those that differ in language use amongst presenters, reporters, compilers, listeners and guest speakers engaged on the Nḓevhetsini episodes. The study found that borrowing, code-mixing, dialectal variants use, and not interpreting the English message to listeners bring challenges in language use in media discourse. Language programmes that promote language should be implemented. Rules that guide language use are important in language preservation. / A hu athu tou vha na vhaḓivhi vha maṅwalwa vhe vha sedzulusa kushumisele kwa luambo kha nyanḓadzamafhungo nga maanḓa kha ngudo ya Nyambo dza Vharema.

The common objective of this project is implementation of software defined radio (SDR) into FPGA. The text contains review and comparison of several hardware concepts intended for SDRs implementation then the methods for digital implementation of various components of radios as the filters, mixers and others are mentioned. Part of the text introduces used hardware platform and describes software support for designing, simulations and implementation into hardware. Significant part of project describes complex of external hardware components as filter, amplifier and control panel designed and built within the project realization. But the main part of project demonstrates design of the software solution of radio receiver. There is specified architecture of radio for FM broadcast receiving, next the more complex systems with carrier recovery algorithm are presented. These systems are able to work with AM, BPSK and QPSK modulations. It is possible to implement all these receivers into hardware and verify their operation. The practical laboratory theme has been outlined within the project run.
