ULTRASONIC RECEIVER FRONT-END

摘要

Systems for receiving one or more echoes are provided. The system (400) comprises a first attenuator (402), a first amplifier (404), and a second attenuator (406). The first attenuator (402) is configured to receive the one or more echo signals (202), and generate a corresponding set of first attenuated echo signals, respectively, based on a number of signal strengths of the one or more echo signals. The first amplifier (404) is configured to receive and amplify the set of first attenuated echo signals to thereby generate a set of first amplified echo signals corresponding to the one or more first attenuated echo signals, respectively. The second attenuator (406) is configured to receive the set of first amplified echo signals and generate a set of second attenuated echo signals corresponding to the set of first amplified echo signals, respectively, based on a number of signal strengths of the set of first amplified echo signals, respectively.
