摘要： The apparatus and method of the present invention provides an ultrasonic object inspection system for measuring the physical properties of a test object comprising a pulse generator for generating and transmitting an electrical pulse signal to a transducer. The transducer receives and converts the electrical pulse signal to an ultrasonic signal, applies the ultrasonic signal to the test object, receives an ultrasonic echo signal from the test object, and converts the ultrasonic echo signal to an electrical echo signal, and transmits the electrical echo signal to a signal processing circuit. The signal processing circuit receives and processes the electrical echo signal and comprises a plurality of signal processing paths. Each of the signal processing paths scales the electrical echo signal to a different degree and comprises a respective analog to digital converter for converting the electrical echo signal to a digital electrical echo signal. The signal processing circuit further comprises a logic circuit for selecting the output of the respective analog to digital converter that provides the digital electrical echo signal having the greatest amplitude without exceeding a predetermined saturation threshold.

摘要： The apparatus and method of the present invention provides a plurality of linear amplifiers simultaneously processing an ultrasonic signal. Each amplifier of the plurality of linear amplifiers has a predetermined gain level suitable for achieving the desired output signal level for input to an analog to digital (A/D) converter for processing. The output of each amplifier is sampled by each respective A/D converter at a very high frequency to convert the analog signal output of each of the linear amplifiers to a digital signal. Logic circuits simultaneously monitor all of the output digital signals from the A/D converters. The logic circuits determine which output of the A/D converters has the greatest linear output and stores the selected output in a memory storage device. The saved output waveforms are subsequently combined into a continuous linear digital output that has a dynamic response range that is approximately the sum of the individual dynamic response ranges of the individual amplifiers and A/D converters. The combined continuous linear digital output waveform may be input to a logarithmic conversion to produce a waveform having a wide dynamic range.

摘要： The invention relates to a method for processing an ultrasonic analog signal (10) representing a reflected ultrasonic wave, wherein the ultrasonic analog signal (10) is fed in a parallel manner into at least two signal paths (A;B) and the ultrasonic analog signal is supplied in each signal path (A;B) to respective amplifiers (20A;20B) whose gains are different from one another. The ultrasonic analog signals (11;11′) which have thus been amplified differently are supplied in each signal path (A;B) to a respective A/D converter (30A;30B) which converts the amplified ultrasonic analog signals (11; 11′) into digital ultrasonic data (12;12′), from which a combined digital ultrasonic signal (15) is reconstructed after further processing steps. According to the invention, a decomposition of the digital ultrasonic data (12; 12′) is carried out in each signal path (A;B) by the first level of a wavelet filter algorithm, and the wavelet coefficients are altered by a threshold analysis. A combined digital ultrasonic signal (15) is then reconstructed from the ultrasonic data thus decomposed, wherein an inverse transformation of the combined ultrasonic signal (15) is carried out by the second level of the wavelet filter algorithm with the altered wavelet coefficients. The invention moreover relates to an associated signal processing unit and an ultrasonic inspection device comprising such a signal processing unit.
