Project Abstract

<p> </p><p>The early transmitter for radio broadcasting is so big and bulky that they do occupy numerous spaces. The circuitries are mainly designed with valves, which are big in sizes.</p><p> With the advent of semiconductor materials such as transistors electronic equipment are now becoming miniaturized such that small transmitters are now becoming handy and compact.</p><p> In line with this we choose to design a complete radio broadcasting equipment tat is compact and existence of semiconductor materials.</p><p> The system units are of two categories namely audio console for the processing and mixing of musicals is basically a condenser microphone. </p><p> The transmitter unit is where the center frequency is provided. All these were designed to be in compact and small manner. This project is aimed at serving a community using a small and compact radio broadcasting equipment with a power watt of 1 watt a community of 1 kilometer in radius should be covered comfortable and the audio production very clear unlike the common noisy FM microphone project.</p><p>&nbsp;</p> <br><p></p>
