Abstract
A transceiver for an ultrasonic imaging device includes a transmit circuit and a receive circuit. The 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. The receive circuit receives the composite signal including the test pulses and the reflected signal and includes a filter circuit. The filter circuit 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.
