| 31. | After vacuum tube oscillators were invented in 1913 by Alexander Meissner the heterodyne receiver replaced the tikker.
|
| 32. | The analogous diversity reception for optical heterodyne has been demonstrated with arrays of photon-counting detectors.
|
| 33. | Other more complex laws may be needed if the network contains nonlinear or heterodyning systems can be approximated.
|
| 34. | Heterodyne detectors are the most commonly used, and most self-build detectors are of this type.
|
| 35. | Calls missed by the heterodyne function, if present, can be seen and measured on the analysis.
|
| 36. | Retuning with an FD detector is not required although this is done with a dual type with heterodyne.
|
| 37. | Another reason for heterodyne processing is that for fixed fractional bandwidth, the instantaneous bandwidth increases linearly in frequency.
|
| 38. | The direct-conversion ( heterodyne ) detector was invented to make continuous wave radio-frequency signals audible.
|
| 39. | Failure of the BFO to match the original carrier frequency when receiving such a signal will cause a heterodyne.
|
| 40. | Continuous wave ( CW ) doppler radar detectors are basically heterodyne detection devices that compare transmitted and reflected beams.
