BLOCK DIAGRAM

A diagram in which the major components of an equipment or a system are
represented by squares, rectangles, or other geometric figures, and the normal order of progression of a signal or current flow is represented by lines [4].

BLOCKED-GRID KEYING

A method of keying in which the bias is varied to turn plate current on and
off [12].

BLOCKING

A condition in an amplifier, caused by overdriving one or more stages, in which the amplifier is insensitive to small signals immediately after reception of a large signal [18].

BOLOMETER

A loading device that undergoes changes in resistance as changes in dissipated power occur [16].

BONDING WIRES

Fine wires connecting the bonding pads of the chip to the external leads of the
package [14].

BOOLEAN

(1) Pertaining to the process used in the algebra formulated by George Boole. (2) Pertaining to the operations of formal logic [13].

BOOLEAN ALGEBRA

A system of logic dealing with on-off circuit elements associated by such
operators as the AND, OR, NAND, NOR, and NOT functions [13].

BOOLEAN LOGIC

See BOOLEAN ALGEBRA [13].

BOUNDARY CONDITIONS

The two conditions that the E-field and H-field within a waveguide must
meet before energy will travel down the waveguide. The E-field must be perpendicular to the walls and the H-field must be in closed loops, parallel to the walls, and perpendicular to the E-field [11].

BRANCH

An individual current path in a parallel circuit [1] [4].
