Fig. 8From: Comparison of synthetic aperture architectures for miniaturised ultrasound imaging front-endsOriginal versus reconstructed envelopes. In a, the original RF signal is overlayed against the ideal I/Q envelop generated in software. Low-rate samples are obtained using the hardware front-end and the I/Q envelop is reconstructed using FRI CS with the following parameters: b \(L=7.\) c \(L=17.\) d \(L=60\)Back to article page
