Abstract
A transmit circuit outputs test pulses to a probe including a transducer to generate an image of a test object. A composite signal including the test pulses and a reflected signal is output by the transducer. A receive circuit receives the composite signal including the test pulses and the reflected signal and includes a filter circuit that filters the test pulses from the composite signal and passes the reflected signal. An impedance of the filter circuit is equal to substantially zero when the reflected signal is within a predetermined frequency range. A clipper circuit limits a magnitude of an output of the filter circuit. An amplifier amplifies the output of the filter circuit and that outputs an amplified voltage. A processing module generates a signal for displaying the image of the test object based on the amplified voltage.
