FREQUENCY STABILITYRefers to the ability of an oscillator to accurately maintain its operating frequency [9]. | |
FREQUENCY SYNTHESISA process that uses hetrodyning and frequency selection to produce a signal [17]. | |
FREQUENCY SYNTHESIZER(1) A frequency source of high accuracy [17]. (2) A bank of oscillators in which the outputs can be mixed in various combinations to produce a wide range of frequencies [18]. | |
FREQUENCY-DETERMINING NETWORKA circuit that provides the desired response (maximum or minimum impedance) at a specific frequency [8]. | |
FREQUENCY-DIVISION MULTIPLEXINGMultiplexing that transmits and receives the full 360 degrees of each sine wave [17]. | |
FREQUENCY-RESPONSE CURVEA curve showing the output of an amplifier (or any other device) in terms of voltage or current plotted against frequency with a fixed-amplitude input signal [8]. | |
FREQUENCY-SHIFT KEYINGFrequency modulation somewhat similar to continuous-wave (cw) keying in AM transmitters. The carrier is shifted between two differing frequencies by opening and closing a key [12]. | |
FRONT-TO-BACK RATIOThe ratio of the energy radiated in the principal direction compared to the energy radiated in the opposite direction [10]. | |
FULL-WAVE RECTIFIERA circuit that uses both positive and negative alternations in an alternating current to produce direct current [6] [7]. | |
FULL-WAVE VOLTAGE DOUBLERConsists of two half-wave voltage rectifiers and is used to reduce the output ripple amplitude [7]. | |
