Abstract

"SISTEMA DE TRANSMISSãO, RECEPTOR CIRCUITO ABSORçãO DE INTERFERêNCIA E MéTODO DE DETECTAR COMPONENTES DE INTERFERêNCIA INCLUìDOS EM UM SINAL E DE REMOVER SUBSTANCIALMENTE, DURANTE UM INTERVALO DE TEMPO, OS COMPONENTES DE INTERFERêNCIA DO SINAL O sistema de transmissão de acordo com a invenção compreende um transmissor (10) e um receptor (12). O transmissor (10) pode transmitir um sinal (11) para o receptor (12). O receptor (12) compreende um circuito de absorção de interferência (20) para detectar os componentes de interferência incluidos no sinal (1 1) e para remover substancialmente, durante um intervalo de tempo (<30>t), os componentes de interferência do sinal (11). O circuito de absorção de interferência (20) é disposto para adaptar o intervalo de tempo (<30>t) dependendo da duração dos componentes de interferência individuais. Preferivelmente, o intervalo de tempo (<30>t) é substancialmente igual à duração dos componentes de interferência individuais. Dessa forma, o fato de os componentes de interferência possuírem uma duração variável, os componentes de interferência podem ser precisamente removidos do sinal desejado (11).
