A modulator constructed so that the carrier is suppressed and any associated carrier noise is balanced out.
Note 1: The balanced modulator output contains only the sidebands.
Note 2: Balanced modulators are used in AM transmission systems.

Synonym balanced line.

1. In a hybrid set, hybrid coil, or resistance hybrid, a circuit used to match, i.e., to balance, the impedance of a uniform transmission line, i.e., twisted metallic pair, over a selected range of frequencies.
Note: A balancing network is required to ensure isolation between the two ports of the four-wire side of the hybrid.
2. A device used between… (Read More →)

Abbreviation for balanced to unbalanced. In radio frequency usage, a device used to couple a balanced device or line to an unbalanced device or line.

1. In communications, the frequency spectrum between two defined limits.
2. A group of tracks on a magnetic drum or on one side of a magnetic disk.
3. A set of frequencies authorized for use in a geographical area defined for common carriers for purposes of communications system management.

Synonym band-stop filter.

Synonym band-stop filter.

A filter that attenuates, usually to very low levels, all frequencies between two non-zero, finite limits and passes all frequencies not within the limits.
Note: A band-stop filter may be designed to stop the specified band of frequencies but usually only attenuates them below some specified level. Synonyms band-elimination filter, band-rejection filter, band-suppression filter, notched filter.

Synonym band-stop filter.

A filter that ideally passes all frequencies between two non-zero finite limits and bars all frequencies not within the limits.
Note: The cutoff frequencies are usually taken to be the 3-dB points.
