rds speed of signaling. The problem was to record Morse dots and dashes in a singleline, using impulses of equal duration. This was accomplished byreversal of current after every marking (positive) impulse. Whena reversal follows quickly, the marking current is suddenly neutralizedand a dot is… … Fig. 53. Delany Receiver proved seriously detrimental to speed, not alone ii high-speed operat-ing but in other methods as well, is utilized as an important adjunctfor operation at speeds approaching the theoretical limit. The tape is perforated in various ways, either by a INIorse key,as shown in…
