Multi-order sampling for digital beamforming of wide-band signals

After proving that the second-order sampling method introduces too much error for beamforming of the wide-band signal generally used in ultrasound imaging systems, we suggest a new multi-order sampling method that significantly reduces sampling error but maintains advantages of the second-order samp...

Zusammenfassung:After proving that the second-order sampling method introduces too much error for beamforming of the wide-band signal generally used in ultrasound imaging systems, we suggest a new multi-order sampling method that significantly reduces sampling error but maintains advantages of the second-order sampling method with relatively simple hardware.
