11. The physical layout of an opto-isolator depends primarily on the desired isolation voltage. 12. This proposed analog isolator is linear over a wide range of input voltage and frequency. 13. This continuous hallway acts as an acoustical isolator and is surfaced with sound absorbing material. 14. A passive isolator can be seen as a mechanical low-pass filter for vibrations. 15. The light from the SLD passes through an optical isolator and subsequently a polarization controller. 16. Is this sufficient RS to say that the original opto-isolator trademark has expired? 17. An opto-isolator connects input and output sides with a beam of light ground wires. 18. To achieve non-reciprocity, an isolator must necessarily incorporate a non-reciprocal material. 19. An isolator will be placed under every load-bearing column and wall below the basement level. 20. A novel idea of a particular optical analog signal isolator was submitted on 3, June 2011.
