REFINING SIGNALS DERIVED FROM FETAL HEARTBEATS |
摘要 |
<p>Circuitry for refinement of fetal heart signals from an ultrasonic (or other mechanical energy) transducer, featuring improved signal processing circuitry connected to the transducer to convert useful information-carrying energy in the transducer output into a refined electrical signal, and improved correlation circuitry for providing an output to a cardiotachometer.</p> |
