11. We do not have any silicon-based active devices . 12. Active devices function as continuous radon monitors; they require a qualified technician for setup and analysis.13. Dongles rapidly evolved into active devices that contained a serial transceiver ( serial or parallel interface. 14. The capabilities and economy of power electronics system are determined by the active devices that are available. 15. Biasing the HBT to obtain an active device , a photo transistor with high internal gain is obtained. 16. It holds the logic signal at a low logic level when no other active device is connected. 17. Testing for radon in the air is accomplished using passive or active devices placed in the building. 18. An attacker can typically eavesdrop within 10 m and 1 m for active devices and passive devices, respectively. 19. Interference, cross chatter, some active devices , and some passive devices all introduce noise or attenuation into the signal. 20. It is an active device , not a resistor . talk ) 18 : 46, 12 December 2007 ( UTC)
