| Abstract: | This paper proposes a new optimum synthesis method of high order active filter network based on second order or third order Butterworth transfer function and presents an example of real time detection of foundamental pitch. The experimental results show that it is convenient in selecting parameters and the system based on this method has steady performance. This method is practical in instrument, engineering testing, signal processing and communication fields. |
