MULTICHANNEL TRANSDUCER DEVICES AND METHODS OF OPERATION THEREOF

摘要

The present disclosure is directed to multichannel transducer devices and methods of operation thereof. One example device includes at least two acquisition modules that have different sensitives and a signal processing stage that generates a blended signal representative of a lower gain signal mapped onto a higher gain signal. One example method of operation includes receiving a first signal from a first sensor having a first sensitivity, receiving a second signal from a second sensor having a second sensitivity that is different from the first sensitivity, generating a blended signal by mapping the second signal to the first signal, outputting the first signal while the first signal is below a first threshold and above a second threshold, and outputting the blended signal when the first signal is above the first threshold and when the first signal is below the second threshold.
