Abstract

a invenção descreve um método de compensação de erro de sinal, compreendendo: receber um primeiro sinal de um primeiro sensor, o referido primeiro sinal indicativo de uma característica de movimento; aplicar uma compensação de erro ao referido primeiro sinal para produzir um sinal de saída; aplicar uma compensação de erro ao referido primeiro sinal para produzir um sinal de saída; receber um segundo sinal a partir de um segundo sensor indicativo da referida característica de movimento; em que a compensação de erro é calculada utilizando a diferença entre o referido sinal de saída e o referido segundo sinal, e o referido fator de ganho variável é calculado utilizando o referido primeiro sinal.
