Being inaudible, the DC component, a _ 0 / 2 \,, and all components with frequencies higher than some finite limit, K f _ 0 \,, are omitted in the following expressions of additive synthesis.
22.
Its drawbacks are that it is not self-clocking and it has a significant DC component, which can be halved by using return-to-zero, where the signal returns to zero in the middle of the bit period.
23.
The DC component of the encoded signal is not dependent on the data and therefore carries no information, allowing the signal to be conveyed conveniently by media ( e . g ., Ethernet ) which usually do not convey a DC component.

25.
Where V ex is the ( DC ) voltage measured by the PMT from the extraordinary wave, and V dc is the DC component of the voltage measured by the PMT for the ordinary wave ( measurement path not shown in the diagram ).
26.
This AC field produces an AC voltage with amplitude proportional to the DC component in the SQUID . The advantage of this technique is that the frequency of the voltage signal can be chosen to be far away from that of any potential noise sources.
27.
Although return-to-zero ( RZ ) contains a provision for synchronization, it still has a DC component resulting in baseline wander during long strings of 0 or 1 bits, just like the line code non-return-to-zero.
28.
This method of combining the power and signal on a single pair of conductors is a form of DC component of the signal is lost, and so when a static acceleration needs to be measured, a " zero Hz " accelerometer must be used instead.
29.
The Manchester coding used for the PHY I and PHY II layers includes the clock inside the transmitted data by representing a logic 0 with an OOK symbol " 01 " and a logic 1 with an OOK symbol " 10 ", all with a DC component.
30.
Many telephones connect to a twisted pair of wires, and use a bias tee to internally separate the AC component of the voltage between the two wires ( the audio signal ) from the DC component of the voltage between the two wires ( used to power the phone ).
