Abstract

Método de Reconhecimento de Sinal Utilizando um Microcontrolador de Baixo Custo. A invenção é relativa a um método de reconhecimento de sinal desde que o sinal seja limitado no tempo e seja periódico, compreendendo a obtenção do envelope, remoção de amostras de valores instantâneos de sua amplitude o qual, por meio de vários parâmetros de duração e suas comparações com diferentes matrizes de referência, permite a identificação da identidade do sinal a um das ditas matrizes por meio do uso de um microcontrolador de baixo custo, dado que o recurso computacional exigido é para realizar operações computacionais básicas incorporadas nos microcontroladores mais simples.
