B
BACK RESISTANCEThe larger resistance value observed when you are checking the resistance of a semiconductor [16]. |
BALANCED MIXERA waveguide arrangement that resembles a T and uses crystals for coupling the output to a balanced transformer [18]. |
BALANCED PHASE DETECTORA circuit that controls the oscillator frequency (afc) [17]. |
BAND-REJECT FILTERA tuned circuit that does not pass a specified band of frequencies [9] [16]. |
BANDPASS FILTERA filter that allows a narrow band of frequencies to pass through the circuit. Rejects or attenuates frequencies that are either higher or lower than the desired band of frequencies [9] [16]. |
BANDWIDTHThe difference between the highest usable frequency of a device (upper frequency limit) and the lowest usable frequency of the device (lower frequency limit) - measured at the half-power points [8] [9] [12] [15]. |
BARRETTERA type of bolometer characterized by an increase in resistance as the dissipated power rises [16]. |
BASE The element in a transistor that controls the flow of current carriers [7]. (1) A reference value. (2) A number that is multiplied by itself as many times as indicated by an exponent. (3) Same as radix. (4) The region between the emitter and collector of a transistor that receives minority carriers injected from the emitter. It is the element that corresponds to the control grid of an electron tube [13]. |
BASE-INJECTION MODULATORSimilar to a control-grid modulator. The gain of a transistor is varied by changing the bias on its base [12]. |
BATTERYA device for converting chemical energy into electrical energy [1]. |
