Systems and methods for processing an analog waveform before it is sampled by an analog-to-digital converter (ADC) for the purpose of multiline beamforming in an ultrasound system are provided. The multiline beamforming is enabled by delaying the same waveform by two different time delays and by re-combining the delayed waveforms. This approach leverages an architecture that can also be used for 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.

An ultrasound probe in which there is local amplification, time gain compensation and digitization of each transducer element output. Inverting arrangements surround the time gain compensation and digitization units, and a synchronous inversion function enables deterministic distortion to be cancelled.
