Abstract :
A second-order recursive digital filter structure that is suitable for implementing bandpass digital filters by cascading second-order sections is proven to be free from all constant-input limit cycles. This filter is derived from a structure proposed by Meerkÿtter and Wegener and requires no additional components.
