Sensibilité et fidélité des oscillateurs autodyne en spectroscopie hertzienne

open access: yes, 1959
The computing of the level of oscillation for an h. f. oscillator, in which there is a modulated absorption of energy, shows that this oscillator acts like a selective low frequency circuit ; damping in this circuit depends on the level of oscillation ...
