dc coupling การใช้

• While the data is DC balanced ( by the encoding algorithm ), the DC coupling is part of the specification.
• However, if DC coupling to the transmitter is not preserved, some transmitters'" monitor detection " features may not work properly.
• It covers the Type-C cable and connector with four power / ground pairs and a separate configuration channel, which now hosts a DC coupled low-frequency RF interference.
• This leads to two significant problems-first, the transmitted DC power leads to higher power losses than other encodings and second, the presence of a DC signal component requires that the transmission line be DC coupled.
• One disadvantage is that the output voltage swing ( typically ?0 20 V ) was imposed upon a high DC voltage ( 200 V or so ), requiring care in signal coupling, usually some form of wide-band DC coupling.
• In electronics, "'direct coupling "'or "'DC coupling "'( also called "'conductive coupling "') is the transfer of electrical energy by means of physical contact via a conductive medium, in contrast to inductive coupling and capacitive coupling.
