Book excerpt: Pulse-frequency modulation is an information encoding technique which has been used in a number of satellites and space probes. The word-error probability for PFM signals is found to be higher when contiguous unmatched filters are used in the detection process than when matched filters are used. The theory of group-coded binary sequences is derived by using a special type of correlation matrix. The experimental results obtained from the spectral analysis of satellite recordings perturbed with random noise are presented to illustrate the noise-immunity characteristic of pulse-frequency modulation.

Available in PDF, EPUB and Kindle. Book excerpt: The research and development undertaken on pulse position and pulse-duration modulation for application in personal-telemetry systems resulted in an improved three-channel, pulse-position, amplitude-modulation-telemetry system with frequency modulation in the FM band. Further experimentation resulted in a seven-channel laboratory model using pulse-duration modulation. The seven-channel equipment allows the monitoring of the electroencephalogram, two leads of electrocardiogram, galvanic-skin resistance, respiration and body temperature, at a distance up to 300 feet. High baseline and amplitude stability are combined with low-power consumption. New microelectronic components make it feasible to reduce the size of the seven-channel transmitting unit to 3.5 by 2.5 by 1 inch, and the weight to about 200 grams, without sacrificing performance. Tape recording of the received signal does not require expensive instrumentation recorders. A portable receiving and recording unit in a small suitcase simplifies the application for field experiments.
Download or read book A Portable Signal Simulator and Decommutator for Pulse Position Modulation Telemetry written by J. Leon Poirier and published by . This book was released on 1966 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the operation of a Pulse Position Modulation telemetry signal simulator and a decommutator that are used for testing and calibrating payloads for Trailblazer II vehicles. The simulator generates dual polarity Pulse Duration Modulation or Pulse Position Modulation modulating signals of several widths. The decommutator performs the functions of decommutation, PPM to PDM conversion, and frame-synchronization signal generation. The units are designed to operate at the standard commutation rate of 900 samples per second with a frame rate of 20 frames per second. (Author).
