Digital Radio Technology and Applications
it DIGITAL RADIO TECHNOLOGY AND APPLICATIONS Proceedings of an International Workshop organized by the International Development Research Centre, Volunteers in Technical Assistance, and United Nations University, held in Nairobi, Kenya, 24-26 August 1992 Edited by Harun Baiya (VITA, Kenya) David Balson (IDRC, Canada) Gary Garriott (VITA, USA) 1 1 X 1594 F SN % , IleCl- -.01 INTERNATIONAL DEVELOPMENT RESEARCH CENTRE Ottawa Cairo Dakar Johannesburg Montevideo Nairobi New Delhi 0 Singapore 141 V /IL s 0 /'A- 0 . Preface The International Workshop on Digital Radio Technology and Applications was a milestone event. For the first time, it brought together many of those using low-cost radio systems for development and humanitarian-based computer communications in Africa and Asia, in both terrestrial and satellite environments. Ten years ago the prospect of seeing all these people in one place to share their experiences was only a far-off dream. At that time no one really had a clue whether there would be interest, funding and expertise available to exploit these technologies for relief and development applications. VITA and IDRC are pleased to have been involved in various capacities in these efforts right from the beginning. As mentioned in VITA's welcome at the Workshop, we can all be proud to have participated in a pioneering effort to bring the benefits of modern information and communications technology to those that most need and deserve it. But now the Workshop is history. We hope that the next ten years will take these technologies beyond the realm of experimentation and demonstration into the mainstream of development strategies and programs. -
Fourier Theory & Practice, Part II: Practice
Fourier Theory & Practice, Part II: Practice Operating the HP 54600 Series Scope with Measurement/Storage Module By: Robert Witte Hewlett-Packard Co. Practice Adding the Measurement/ Storage module to the scope adds additional waveform math capability, including FFT. These functions appear in the softkey menu under the ± (math) key. There are two math functions available, F1 and F2. The FFT function is available on Function F2. Function F2 can use function F1 as an operand, allowing an FFT to be performed on the result of F1. By setting function F1 to Channel 1 - Channel 2, and setting F2 to the FFT of F1, the FFT of a differential measurement can be obtained. The Measure- ment/Storage Module operating manual provides a more detailed discussion of these math functions. The scope can display the time domain waveform and the frequency domain spectrum simultaneously or individually. Normally, the sample points are not connected. For best frequency domain display, the sample points should be connected with lines (vectors). This can be accomplished by turning off all (time domain) channels and turning on only the FFT function. Alternatively, the Vectors On/Off softkey (on the Display menu) can be turned On and the STOP key pressed. Either of these actions allow the frequency domain samples to be connected by vectors which causes the display to appear more like a spectrum analyzer. The vertical axis of the FFT display is logarithmic, displayed in dBV (decibels relative to 1 Volt RMS). dB V = 20 log (VRMS) Thus, a 1 Volt RMS sinewave (2.8 Volts peak-to-peak) will read 0 dBV on the FFT display. -

NTSC Specifications
NTSC Modulation Standard ━━━━━━━━━━━━━━━━━━━━━━━━ The Impressionistic Era of TV. It©s Never The Same Color! The first analog Color TV system realized which is backward compatible with the existing B & W signal. To combine a Chroma signal with the existing Luma(Y)signal a quadrature sub-carrier Chroma signal is used. On the Cartesian grid the x & y axes are defined with B−Y & R−Y respectively. When transmitted along with the Luma(Y) G−Y signal can be recovered from the B−Y & R−Y signals. Matrixing ━━━━━━━━━ Let: R = Red \ G = Green Each range from 0 to 1.
