The subject index has been arranged in such a manner as to avoid lengthy listings under main topics. For instance, under the main topic "scales," the reader is referred to specific main entries for specific types of scales; and under the main topic "specifications and tolerances," the reader is referred to specific main entries for specifications and tolerances for specific types of weighing or measuring devices. Since all topics presented at the National Conference relate to either weight or measure, the main topic "weights and measures" appearing in the previous index has been eliminated. Also, the main topic "resolutions" appearing in the previous index has been eliminated, as any resolution passed on a specific topic is listed under that topic.The speaker index is arranged alphabetically by name of speaker. Under each name, the addresses of the speaker are listed chronologically.The citations to the reports and the page numbers are given as follows: The report number precedes the comma, and the page number in the report follows the comma. Each set of report and page numbers is separated by a semicolon.A list of the Conference Reports and their availability appears on page 41 1 INDEX BY SUBJECTS A Acetylene gas, sale and marking, 39, 63.

This paper is concerned with a systematic approach to the design of the “linear channel” of a repeater for a digital fiber optic communication system. In particular, it is concerned with how one properly chooses the front‐end preamplifier and biasing circuitry for the photodetector; and how the required power to achieve a desired error rate varies with the bit rate, the received optical pulse shape, and the desired baseband‐equalized output pulse shape. It is shown that a proper front‐end design incorporates a high‐impedance preamplifier which tends to integrate the detector output. This must be followed by proper equalization in the later stages of the linear channel. The baseband signal‐to‐noise ratio is calculated as a function of the preamplifier parameters. Such a design provides significant reduction in the required optical power and/or required avalanche gain when compared to a design which does not integrate initially. It is shown that, when the received optical pulses overlap and when the optical channel is behaving linearly in power,1 baseband equalization can be used to separate the pulses with a practical but significant increase in required optical power. This required power penalty is calculated as a function of the input and equalized pulse shapes.
