There are three types of AC coupling
: resistive, capacitive and inductive.
Begin by reading and understanding the description in 1149.6 of possible implementations of AC coupling
on high-speed 10 signals.
The last RF stages of the receiver are active low pass filters with an AC coupling
for the I and Q outputs.
allows us to use distributed arrays of more than 4000 junctions that have larger output voltage as compared to the previously used lumped arrays with only 250 junctions.
The Model: DCD is innovatively designed whereby DC isolation is achieved and AC coupling
is maintained, ensuring electrical grounding criteria remains effective.
Additional features include support for both 62.5[micro] and 50[micro] industry standard MTP/MPO multi-mode ribbon fibers; and the data I/O is AC coupling
, PECL, LVDS and CML compatible.
For example, AC coupling
is used to block the DC component of a waveform, but good low-frequency response requires a large value capacitor and its attendant charging time.
However, other modulation schemes present a peak at DC, and capacitive AC coupling
will lead to significant information loss, hence considerably degrading the bit error rate (BER).
Researchers recently have demonstrated an ac coupling
technique that increases the useful output voltage for metrology measurements.
If you use a combination DC/AC current probe, set the oscilloscope for AC coupling
to prevent measurement error that would result from a DC offset within the probe.
