RATIO OF TRANSMITTED POWERSThe power ratio (FSK versus AM) that expresses the overall improvement of FSK transmission when compared to AM under rapid-fading and high-noise conditions [12]. | ||
RC CONSTANTTime constant of a resistor-capacitor circuit; equal in seconds to the resistance value in ohms multiplied by the capacitance value in farads [2] [9]. | ||
RC DIFFERENTIATORAn RC circuit in which the output is taken from the resistor [9]. | ||
RC FILTERA filter used in applications where load current is low and constant, and voltage regulation is not necessary [7]. | ||
RC INTEGRATORAn RC circuit in which the output is taken from the capacitor [9]. | ||
RC NETWORKA circuit containing resistance and capacitance arranged in a particular manner to perform a specific function [9]. | ||
RC OSCILLATORAn oscillator in which the frequency is determined by resistive and capacitive elements [9]. | ||
REACTANCEThe opposition offered to the flow of an alternating current by the inductance, capacitance, or both, in any circuit [2]. | ||
REACTANCE AMPLIFIERA low-noise amplifier that uses a nonlinear variable reactance as the active element instead of a variable resistance. Also called a parametric amplifier [11]. | ||
REACTANCE TUBEA tube connected in parallel with the tank circuit of an oscillator. Provides a signal that will either lag or lead the signal produced by the tank [12]. | ||
