Modulation:
The carrier amplitude is reduced to 25 % at the beginning
of each second for 100 ms (binary zero) or 200 ms (binary
one) duration, excepting the 59th second.
Time Code Format: (based on in-
formation of Deutsche Bundespost)
It consists of 1 minute time frames. No modulation at the
beginning of the 59th second to recognize 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. Further there are
5 additional bits R (transmission by reserve antenna), A1
(announcement of change–over to the summer time), Z1
(during the 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.
