Abstract:
1. A biquad infinite impulse response (BIIR) system, comprising: a first delay line configured to receive at least one input data sample and to generate a plurality of delayed input samples as a function of the input data sample; a second delay line including a plurality of delay elements connected together in a series configuration, an input of a first one of the delay elements receiving at least one output data sample of the BIIR system, the second delay line configured to generate a plurality of delayed output samples; and a summation element configured to generate the at least one output data sample of the BIIR system as a function of an addition of at least a first signal and a second signal and a subtraction of at least a third signal, the third signal comprising at least a first delayed output sample generated by the second delay line multiplied by a first prescribed value, the first delayed output sample and the at least one output data sample of the BIIR system being temporally nonadjacent to one another, whereby the BIIR system is configured to eliminate a dependency between the at least one output data sample of the BIIR system and a temporally adjacent delayed output sample generated by the second delay line.
