The logo shows a 2-port-adaptor for Wave-Digital-Filter designs, a technique to design efficient and inherently stable digital IIR filters that has not received the attention it deserves.

For details on the filter design, please refer to (1) for the theoretical background, and to (2) for the practical applications.
