Abstract
This senior project presents the data transmission over the SCA (Subsidiary Communications Authorization) channel authorized for use in FM and TV broad casting to provide a one-way digital transmission channel for teletext-type service. The rules, such as FCC rules have been used for place FSK information signal on SCA channel in order to have no interference be caused to the normal stereo transmissions and solved the instantaneous frequency limit problem on this channel. In addition to data communication c
hannel interface, the data terminal equipments that composed of RS-232C interface, CPU, Memory, and CRT controller have been designed. Data communication theory and Modulation techniques are provided. Operating software are also presented which can used for operate and test the system.
