Modulation
The carrier amplitude is reduced to 25% at the
beginning of each second for a period of 100 ms
(binary zero) or 200 ms (binary one), except the
59
Time-Code Format (based on Information
of Deutsche Bundespost)
The time-code format consists of 1-minute time
frames. There is no modulation at the beginning of
the 59
