Abstract :
Allpass digital filters are major building blocks in many digital filter structures. A new pipelined architecture for the 2nd order allpass section based on the 3-port series adaptor is presented. It is shown how to maximise the sample rate whilst applying the minimum level of pipelining. The new architecture has up to double the maximum sample rate of other structures
