This paper aims to present two ways to design and implement numerical filters. The first is the classic or hand-coded method, which involves the implementation of a computational algorithm in C, while the second is automatically generated code. Both FIR and IIR filters are implemented and based on the results obtained, the differences between them discussed. We highlight the advantages and disadvantages of each method of implementation and the costs in terms of design time, memory, performance. Both implementation variants present satisfactory results and meet the required requirements, the choice of one of them depends on the application used and the programming experience.
