It therefore tries to record the signal containing the extra sync pulses.
In this method, the current wave completes but a new waveform is generated at the sync pulse.
So the measuring equipments measure only the highest level (sync pulse) of a line waveform which is 100%.
The duration of the sync pulse is 4.7 μs.
A cable conducts the sync pulse from camera to sound recorder.
Specifically, the sync pulses (being "blacker than black") result in maximum power from the transmitter.
The output power of the transmitter is defined as the power during sync pulse.
The values 0 and 255 are used to encode the sync pulses.
In signal processing terms, it compensates for the fall time and settling time following the sync pulse.
The format of the horizontal sync pulse varies.
