FIR Filter Design Method Based on LASSO to Adjust the Number of Non-zero Coefficients
Clemens Klöck · 2021
In this document a new FIR filter design algorithm is proposed. The algorithm gives the designer a set of filters which differ in the approximation of the ideal filter characteristic and the number of none-zero elements. The designer can choose a filter based on proposed filter selection criteria which filter is suitable for the tradeoff between approximation as well as processing power and storage capacity.
