Polarity-Sensitive Detection of Pulsed Ultrasound Signals
The signal-processing methods to be described, permit the extraction of more information from the H.F.-echo signal than the traditionally used envelope detector does. The latter detector ignores for instance the polarity of the reflection, which is obviously a part of the information as polarity represents the “most significant bit” of a signal.1
