| 11. | They are all topologically equivalent to toroids.
|
| 12. | Baluns can be made using ferrite toroid cores or even from the coax feedline itself.
|
| 13. | This design is based on a toroid ( the same shape as a doughnut ).
|
| 14. | The toroid should be repositioned or covered with tape or something to blunt its edge.
|
| 15. | The output stage is top left, the output chokes are the two yellow toroids underneath.
|
| 16. | In this context a toroid need not be circular and may have any number of holes.
|
| 17. | The first three categories are all convex, whereas Stewart toroids have polygonal-faced tunnels.
|
| 18. | They source toroids from Nuvotem Talema in Ireland since H & F ceased trading in 1993.
|
| 19. | Many other lower symmetry toroids can also be constructed by removing a subset of these dissected components.
|
| 20. | Supercoiled DNA forms two structures; a plectoneme or a toroid, or a combination of both.
