Abstract :
Computer-aided responses of an electronically tunable bandpass filter by two different methods are presented. Significantly different results are possible for the same circuit if different methods are used due to the nonuniqueness of the Z-to S domain transformation. It is also demonstrated that digital implementation of tunable bandpass filters using the difference equation approach is possible
