Coherence resonance in uhf devices with long interaction

Sadovnikov Sergej Aleksandrovich, Saratov State University

This work presents results of experimental studies of coherence resonance phenomenon in UHF devices with long interaction (TWT and BWO). Basic properties of this phenomenon were investigated. Discovered suppression effect of resonant response on external noise by external harmonic signal. This suppression effect can be used to increase signal-tonoise ratio in system’s output. Specific features of coherence resonance phenomenon in long-interaction devices also noted.
