The use of frequency modulation radio in the public schools of the United States

Unknown Date (has links)
"When the subject of the use of FM radio in the public schools was suggested by the writer as a subject for a research paper one of the first comments made by a fellow student was, 'Radio is a dead issue. Television has already made it out of date.' This comment immediately made the subject a challenge. Had we in America, in less than a generation, advanced to rapidly that one of the world's greatest media of communication was already out of date? The writing of this paper is an effort to answer that question, and in answering it to present a picture of the status of frequency modulation broadcasting in the public schools throughout the nation today"--Introduction. / Typescript. / "August, 1953." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Arts." / Advisor: John W. Mitchell, Professor Directing Paper. / Includes bibliographical references (leaves 67-68).

Decoder Board Hardware/Software Development in Wireless Interactive Video Data Service System

Goedde, Todd William 06 December 1997 (has links)
The Interactive Video Data Service (IVDS) system allows consumers to browse the Internet, request information on products or services, make purchases, indicate preferences, and perform other interactive applications. To provide this service, the IVDS system has three subsystems: Consumer Control (CC), Cell Repeater (CR), and Host subsystem. In the CC subsystem, an IVDS transceiver box is placed near a television set. Once the consumer sends a command to the transceiver box using a standard television/VCR/Cable remote control, the transceiver box receives information embedded in the television audio, and then transmits the information to the CR subsystem as a radio frequency (RF) spread spectrum message. The CR subsystem decodes the spread spectrum message and forwards it to the Host subsystem for processing. Located in the CR subsystem, a custom designed circuit board, called the decoder board, uses surface mounted components to decode and packetize the spread spectrum message for transfer to the CR main processor. This paper provides a functional description of the hardware components on the decoder board, and describes the hardware/software developed for interfacing the decoder board to the radio receiver and to the CR main processor. Hardware modifications were needed to correct timing problems between components. Software was developed to initialize the components for downconverting, despreading, and demodulating spread spectrum messages, and to packetize them for transfer to the CR main processor. This paper also discusses the tests used to verify both the performance of the decoder board software and the operation of the hardware components. / Master of Science
