recursive filter

(electronics)
A digital filter that has feedback; that is, its output depends not only on present and past input values but on past output values as well.

Table I notes that in the implementation of the filter unit 34% of embedded multipliers, 1% of the logic elements and 0 % of bits of memory are used, this is evidence that space is available within FPGA to increase the degree of parallelism in the design and simultaneously use multiple filter units, which would provide the coefficients for higher levels in less time occupying all the available multiplier, in applications where FPGA is used only for implementation phase of this transformation is a viable option, but in applications where you need to implement additional functions on the FPGA using the recursive filter units for the calculation of the following levels of transformation is necessary.
