temperature-controlled chamber used to maintain the quartz crystal in electronic crystal oscillators at a constant temperature, in order to prevent changes in the frequency due to variations in ambient temperature
pulsar
cellular automaton pattern
electronic oscillator
electronic circuit that produces a repetitive, oscillating electronic signal
anharmonic oscillator
