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 59th second.
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 59th
second to indicate the switch over to the next 1-minute
time
frame.
A
time
frame
contains
BCD-coded
information of minutes, hours, calendar day, day of the
week, month and year between the 20th second and 58th
second of the time frame, including the start bit S (200
ms) and parity bits P1, P2 and P3. Furthermore, there are
5 additional bits R (transmission by reserve antenna), A1
(announcement of change-over to summer time), Z1
(during summer time 200 ms, otherwise 100 ms), Z2
(during standard time 200 ms, otherwise 100 ms) and A2
(announcement of leap second) transmitted between the
15th second and 19th second of the time frame.
