| 1. | In part, a decoder is a narrow bandpass filter.
|
| 2. | Stacked inductive and capacitive meshes can be used to make bandpass filters.
|
| 3. | Bandpass filter applied to signal ( middle diagram ).
|
| 4. | Suitable external bandpass filters are required to photograph in IR or UV wavelengths.
|
| 5. | Bandpass filters are normally designed for normal incidence.
|
| 6. | It separates the wavelengths using passive optical components such as bandpass filters and prisms.
|
| 7. | In practice, no bandpass filter is ideal.
|
| 8. | Examples of bandpass filters are the Lyot filter and the Fabry-P�rot interferometer.
|
| 9. | Multiple bandstop filters can always be expressed in terms of a multiple bandpass filter.
|
| 10. | This requirement implies that a radio astronomer must restrict signals through a bandpass filter.
