Applying the criterion of the work state of operational amplifier , the stable operating condition of voltage - controlled voltage source filter 2 is proved in detail and the condition that the filter can be used as the sinusoidal oscillator is given 摘要利用運放工作狀態(tài)的判據(jù),系統(tǒng)地證明? 4種二階壓控電壓源型濾濾器穩(wěn)定工作的條件,同時給出了用作正弦波振蕩器的條件。
On the basis of physical concept , applying mathematical method , the condition that the problem can be transformed from the voltage - controlled voltage source lpf of two orders to the sinusoidal oscillator is proved and the calculation formula of oscillatory frequency is presented 摘要以物理概念為基礎(chǔ),利用數(shù)學(xué)手段證明?二階壓控電壓源lpf轉(zhuǎn)化為正弦波振蕩器的條件,同時給出了振蕩頻率的計算式。
( 2 ) piece - wise linear ( pwl ) circuit realizations of the class - di - a chaos generator are suggested . in the circuit realizations , only one nonlinear element is needed , that is , only a three - segment pwl voltage - controlled vokage source or a two - segment pwl voltage - controlled voltage source is needed . in the context of the whole circuit structure , this circuit realization is more complex than that of chua ' s circuit , but in the context of the complexity of the nonlinear element employed , it is the most simple chaos circuit while realized by a two - segment pwl element ( 2 )對本文所提出的第- a種新的單渦旋混沌模型進(jìn)行了分段線性電路實驗研究,其分段線性電路實現(xiàn)只需一個非線性器件,即一個三段線性電壓控制電壓源或兩段線性電壓控制電壓源,從整體電路結(jié)構(gòu)來看,它比蔡氏電路要復(fù)雜,然而它可以采用兩段線性電壓控制電壓源來實現(xiàn),因而就非線性器件的復(fù)雜程度而言,它是最簡單的混沌發(fā)生器。
