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^th second.
Time-Code Format (based on Information
of Bundesamt für Metrologie und
Akkreditierung (METAS))
The time-code format consists of 1-minute time
frames. There is no modulation at the beginning of
the 59^th 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 20^th second and 58^th 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), A (announcement of change-over to
summer time), E (during summer time 200 ms,
otherwise 100 ms), H (during winter time 200 ms,
otherwise 100 ms) and L (announcement of leap
second) transmitted between the 15^th second and
19^th second of the time frame.
