O
oscillator
a device that generates a fixed frequency signal. An oscillator most
often generates signals by using oscillating crystals, but also may use
tuned networks, lasers, or atomic clock sources. The most important
specifications on oscillators are frequency accuracy, frequency
stability, and phase noise.
output impedance
the measured resistance and capacitance between the output terminals
of a circuit
