摘要
Signals have parity test bits, and relays are provided in the five signal channels. The decoder recognizes single errors in the transmitted BCD-coded signals. In order to decode a signal three from four change-over contacts (20) of a first relay, three from four change-over contacts (21) of a second relay and one of four contacts (22) of a third relay are linked to form ten circuits (0, 1-9). One from four contacts (23) of a fourth relay, and two from four contacts (p) of a fifth relay are combined in four circuits (8; 9; 1, 2, 4, 7; 0, 3, 5, 6). In order to recognize single errors, all the remaining contacts of the five relays are combined in a circuit (F).
