又是技术控 技术永远都是技术 因为这个变压器加电阻的分频方式,它用在前级之前,工作电流非常小,所以频响曲线影响不大,实质的原理只是利用不同频率在电阻和电感上的分压不同的基础原理,所以是真正的分频,任何时点,这两路信号都是互补的。常规的分频器实质并非分频器,而只是两路过滤器的合并,两路信号绝非互补关系。因此...
by traditional Lyapunov stability theorem and Barbalat lemma, which are used to prove the error vector???approaches zero, as time approaches infinity. However, the core question???why the estimated or given parameters also approach to the uncertain parameters???remains without answer. By the new...
