transmitted pulse
1.In order to convenience the users of BPL time signals, it is suggested to add UTC clock display and DUT_1 time messages to the time signals transmitted. A method of master transmission station mark-pulse coding and the suggested pattern of the coding are recommended in this paper, which would offer more effective time service without interfering the existing use.
2.The quantized samples can be encoded in various formats, such as Pulse Code Modulation (PCM), to be stored or transmitted.
3.Taking the SIEMENS SICLOCK GPSDEC system as the example, the time synchronization was realized with ASCII message format and DCF77 signal, pulse signal transmitted by RS-232 interface or TTY current loop interface.
