Asymmetrical signal transmission

With asymmetrical signal transmission or asymmetrical signal transmission , English single-ended signaling , the electrical signal transmission takes place through a voltage that changes with respect to a reference potential . Typically a shielded cable is used for this ( coaxial cable ).

The asymmetrical signal transmission is the opposite of the symmetrical signal transmission .

Unbalanced signal transmission is the simplest type of data transmission. A conductor carries a voltage that changes depending on the signal in relation to a reference line, usually ground , which is also connected to other circuit parts. If several signals are to be transmitted, only one reference line is used. This simplifies the wiring and electronics, but is more susceptible to electromagnetic interference.

Typical areas of application are

• sound transmission in non-professional and partially semi-professional environments ( cinch , DIN , jack plugs (also used for symmetrical signal transmission), S / PDIF ),
• analog video transmission ( SCART ),
• digital transmission ( EIA-232 (RS-232), IEEE 1284 (Centronics), HDBaseT , 10BASE2 - and 10BASE5 - Ethernet ) and
• the transmission of high-frequency signals from antenna , LNB or the BK network to radios , televisions and tuners .
