An acoustic scanning method and apparatus implemented by transmitting ultrasonic pressure waves and receiving return echoes on a set of spatially non-overlapping acoustic lines scanned along a curved linear transducer array with the active acoustic lines shifted and steered so that e
An approach is presented for relaxing the oversampling requirements in a .DELTA..SIGMA. modulator based analog-to-digital converter through parallel .DELTA..SIGMA. modulation channels with decimation filtering and modulation by sequences u.sub.r (n) and v.sub.r (n) derived, for example,
