RL INTEGRATORAn RL circuit in which the output is taken from the resistor.
SELECTIVITYThe ability of a circuit to discriminate between frequencies.
SERIES-FED OSCILLATORAn oscillator in which dc power is supplied to the amplifier through the
tank circuit or a portion of the tank circuit.
SERIES LIMITERThe diode is connected in series with the output and the output is taken across the
resistor. Either the positive or negative alternation of the input wave is eliminated.
SERIES-NEGATIVE LIMITERThe diode is connected in series with the output and the output is
taken across the resistor. Eliminates the negative alternation of the input wave.
SERIES-PARALLEL CIRCUITA circuit in which two or more parallel or series combinations are in
series with each other.
SERIES-POSITIVE LIMITERThe diode is connected in series with the output and the output is
taken across a resistor. Eliminates the positive alternation of the input wave.
SERIES-RESONANT CIRCUITA resonant circuit in which the source voltage is connected in series
with a capacitor and an inductor (also in series) to furnish a low impedance at the frequency at which
the circuit is resonant.
SHAPING CIRCUITA circuit which alters the shapes of input waveforms.
STEP-BY-STEP-COUNTERA counter which provides an output for each cycle of the input in one-
SHUNT-FED OSCILLATORAn oscillator which receives its dc power for the transistor or tube
through a path both separate from and parallel to the tank circuit.
TANK CIRCUITA tuned circuit used to temporarily store energy. Also referred to as a parallel-
TICKLER COILSmall coil connected in series with the collector or plate circuit of a transistor or tube
and inductively coupled to a base or grid-circuit coil to establish feedback or regeneration.
TIME CONSTANTTime required for an exponential quantity to change by an amount equal to .632
times the total change that can occur.
TRIGGERShort pulse, either positive or negative, which can be used to cause an electrical function to
TUNED CIRCUITCircuit consisting of inductance and capacitance which can be adjusted for
resonance at a desired frequency.
UPPER-FREQUENCY CUTOFFThe highest frequency a circuit can pass.
