Abstract
Systems and methods for filtering an analog waveform before it is sampled by an analog-to-digital converter (ADC) in an ultrasound system are provided. The waveform can be filtered by delaying the same waveform by two different time delays and combining the delayed waveforms to effectively cancel out the fundamental components, thereby providing more sensitive detection of harmonic components in received echo signals. This filtering approach leverages an architecture that can also be used for multiline beamforming to perform the temporal filtering, in which a single acoustic signal can be read out of the ARAM twice, separated by time, taking advantage of the fact that the ARAM allows for non-destructive read operations.
