Abstract
Digital processing of acoustic signals introduces pulses to measurement of impedances and transfer functions of ultrasonic systems. Digital impulse measurements of electroacoustic transducers described in the paper are based on comparison between the Fourier transforms of the input signals and the responses of the ultrasonic systems. Measuring signals consisting of two separate parts have been used where the power piezoelectric transducer is the input part of the system. Similarly, the output response also has two parts.
