Abstract :
An inner ear degree-two cochlea section, which encompasses complex transmission zeros, is realized completely in hardware. In doing this, standard complex two port filters are extracted to a real four port network. A new digital switched current circuit is used with improved clock feed through delay portions. A complex lattice portion is simulated in both Spice and Matlab with accurate results
