摘要
由于数字均衡器的具有灵活性,精度高,方便更改等优点,在水声学中有着广泛的应用。在每次水声系统测试中,根据频谱均衡要求,使用MATLAB计算出的均衡参数,通常使用仿真器连接数字均衡器电路板的JTAG口,更新FLASH存储器中的程序代码。这种方法操作繁琐、费时。这就需要我们结合水声调试对均衡参数更新的要求,研究一种可以远程实时更新数字均衡器均衡参数的实现方法。实验结果表明该均衡参数更新方法有效、可行。
Because the digital equalizer has such advantages like flexibility, high accuracy, and easy to be changed, it has widely used in underwater acoustics area. In each underwater acoustics test, based on the spectral equilibrating requirements, and using the equilibrium parameter calculated by MATLAB, a simulator is usually used to connect the JTAG interface on digital equalizer circuit board for updating the program code stored in FLASH. This method is cumbersome and time-consuming. Based on the request of equalizing parameter updating in underwater acoustics test, a method of remote real-time updating frequency equalization is investigated. The experimental results show that the proposed parameter update method is effective and feasible.
