| 1. | OK, a moon phase detector would be good for researchers to have.
|
| 2. | Instead of a simple phase detector, the design uses a harmonic mixer ( sampling mixer ).
|
| 3. | The expression suggests a quadrature phase detector can be made by summing the outputs of two multipliers.
|
| 4. | Some PLLs also include a divider between the reference clock and the reference input to the phase detector.
|
| 5. | A phase detector compares two input signals and produces an error signal which is proportional to their phase difference.
|
| 6. | A phase detector is a nonlinear device whose output represents the phase difference between the two oscillating input signals.
|
| 7. | PLLs may include a divider between the oscillator and the feedback input to the phase detector to produce a frequency synthesizer.
|
| 8. | A phase detector suitable for square wave signals can be made from an exclusive-OR ( XOR ) logic gate.
|
| 9. | In these systems, the signal was not fed directly to the display, but first fed into a phase detector.
|
| 10. | Likewise, if the phase creeps ahead of the reference, the phase detector changes the control voltage to slow down the oscillator.
