REACTANCE-TUBE MODULATORAn FM modulator that uses a reactance tube in parallel with the oscillator tank circuit [12]. | |
RECEIVER(1) The object that responds to the wave or disturbance. Same as DETECTOR [10]. (2) Equipment that converts electromagnetic energy into a visible or an audible form [17]. (3) In radar, a unit that converts RF echoes to video and/or audio signals [18]. | |
RECEIVER SENSITIVITY(1) The degree to which a receiver can usefully detect a weak signal. (2) The lower limit of useful signal input to the receiver [18]. | |
RECEIVER TRANSFER SWITCHBOARDEquipment used to transfer receiver audio outputs to remote control station audio circuits [17]. | |
RECEIVING ANTENNAThe device used to pick up the RF signal from space [10]. | |
RECEIVING ENDSee OUTPUT END [10]. | |
RECEPTIONThe instant when an electromagnetic wave passes through a receiver antenna and induces a voltage in that antenna [17]. | |
RECIPROCAL(OF A QUANTITY)—The value obtained by dividing the number 1 by that quantity [1]. | |
RECIPROCITYThe property of interchangeability of the same antenna for transmitting and receiving [10] [11]. | |
RECOVERY TIMEIn a radar, the time interval between the end of the transmitted pulse and the time when echo signals are no longer attenuated by the tr gap [18]. | |
