6. 4- DESIGNING AND IMPLEMENTATION ANALOGUE OF QUADRATIC TRANSFER FUNCTION 4-1- DESIGNING AND IMPLEMENTATION BY DIFFERENTIAL DESCRIPTIVE EQUATIONS 6 In accordance with Quadratic equation which is in Laplace domain, first of all, it should be concerted to time domain. In the time domain, the derivation is used and the derivation is sensitive to the noise. So, the derivation should be converted to differential equations.
