By comparison, a full-wave rectifier draws AC current from the source ( with essentially no DC component ) so the transformer operates normally.
12.
Air gaps are also used to keep a transformer from saturating, especially audio-frequency transformers in circuits that have a DC component flowing in the windings.
13.
Assuming that the input signal is zero-mean ( i . e . contains no DC component ), minimal distortion is attained when this constant is set to zero.
14.
The top row is all ones ( scaled by 1 / \ sqrt { 8 } for unitarity ), so it " measures " the DC component in the input signal.
15.
Diphase modulation combined with signal conditioning that eliminates the dc component of the signal, enhances timing recovery, and facilitates transmission over voice frequency ( VF ) circuits or coaxial cables.
16.
This both reduces the size and power requirements of the energizing source and increases the resolution of the resistive component ( near DC component ) of dielectric loss ( not the capacitive component ).
17.
If the output of the filter is to be used for an application such as pattern recognition, this DC component is undesirable because it gives a feature that changes with the average value.
18.
Bias is a technique by which active devices are set to operate in a particular region, or by which the DC component of the output signal is set to the midpoint between the maximum voltages available from the power supply.
19.
Some line codes are "'digital baseband modulation "'or "'digital baseband transmission "'methods, and these are baseband line codes that are used when the line can carry DC components.
20.
The above equation has an AC component at twice the frequency of the original signals ( second term ) and a DC component ( first term ) whose value is related to both the amplitude and phase of the input signal.
