Signal Processing Clause Samples

Signal Processing. For each recorded sample the autopower spectrum shall be determined, using a ▇▇▇▇▇▇▇ window and at least 66.6% overlap averages. The reported speed is the average of the speed during the time sample. In case of test method (A) the [four] determined spectra per test speed shall be energetically averaged. The resulting average spectrum per test speed shall be used for the further calculation. In all other cases the derived frequency spectrum shall directly be used for the further calculation. The reported speed is the average of the [four] measurements.

The frequency resolution shall be chosen sufficiently narrow to allow a separation of the frequency shift per target condition. The reported speed per sample segment is the average vehicle speed over the time of the sample segment. In case of test method (A) the frequency that is intended to be changed with the speed shall be determined per sample segment. The reported frequency per target condition fi,speed shall be the mathematical average of the frequencies determined per measurement sample and rounded to the nearest integer. The reported speed per target condition shall be the mathematical average of the [four] sample segments, rounded to the first decimal.

The frequency resolution shall be chosen to be sufficiently narrow as to allow a separation of the frequency shift per target condition. The reported speed per sample segment is the average vehicle speed over the time of the sample segment rounded to the first decimal place. In case of test method (A) the frequency that is intended to be changed with the speed shall be determined per sample segment. The reported frequency per target condition fspeed shall be the mathematical average of the frequencies determined per measurement sample and rounded to the nearest integer. The reported speed per target condition shall be the mathematical average of the four sample segments.

Signal Processing. Echoes received by the piezoelectric element are too weak to be displayed directly after reception and so need to be amplified. The first step is to amplify all returning echoes by the same factor, this being represented by the overall gain on an ultrasound machine. Because of tissue attenuation echoes returning from deeper tissues are weaker than those from more superficial interfaces. In order to achieve the aim of B – mode imaging, i.e. to relate brightness on the screen to the strength of returning echoes, echoes that take longer to arrive are amplified more to counteract the effect of tissue attenuation. Returning echoes are then compressed and digitised so that the analogue signal received by the transducer is converted to a binary number representing the signal amplitude. In order to correctly display a B-mode image, apart from echo amplitude and the position of the scan line relative to other returning echoes, it is necessary to know the range of the echo to be displayed.

  • Subprocessing The data importer shall not subcontract any of its processing operations performed on behalf of the data exporter under the Clauses without the prior written consent of the data exporter. Where the data importer subcontracts its obligations under the Clauses, with the consent of the data exporter, it shall do so only by way of a written agreement with the subprocessor which imposes the same obligations on the subprocessor as are imposed on the data importer under the Clauses. Where the subprocessor fails to fulfil its data protection obligations under such written agreement the data importer shall remain fully liable to the data exporter for the performance of the subprocessor's obligations under such agreement.
