| Delay distortion is the difference in delay between the frequency under test and a reference frequency near the center of the circuit passband. |
| Any RF that falls within a receiver's passband that's hot enough can open squelch and pass noise. |
| To estimate the power in individual frequency bands, fifth order Butterworth passband filter functions were used. |
| A second bandpass filter of the at least two disparate bandpass filters has as a passband a second frequency band. |
| The passband filters used were of 546, 490 and 360 nm for green, blue and ultraviolet light, respectively. |
| All radiation outside the hydrogen passband falls within the noise of the instrument. |
