A technical article about phase noise in signal sources due to phase modulation.

Attached time signal systems generally use audible tones or phase modulation of the carrier wave.

The most widely used modulation scheme is continuous phase modulation.

Other techniques, such as phase modulation or changing the phase of the carrier signal, are also used.

Modification in phase according to low frequency will give phase modulation.

Since phase modulation is employed, higher order terms are also generated.

Otherwise the phase modulation would not work.

In a second step dispersion leads to a transformation of the phase modulation into a power variation.

Additional non-timing data is sent by phase modulation during the rest of each second.

But the second marker (and data bit) is always preceded by 100 ms without any phase modulation.
