TWO-CHANNEL METHOD FOR CONTINUOUSLY DETERMINING AT LEAST ONE OUTPUT SIGNAL FROM VARIABLE INPUT SIGNALS

摘要

The invention relates to a two-channel method for determining at least one output signal from variable input signals of sent by a transmitter, using two independent channels and consisting in alternately guiding the input signals to said channels, wherein a multiplexer (20) is used for switching said channels. A microprocessor (16-1) contained in said channels delivers input test signals transmitted to the channel not currently receiving any variable input signal. Said channel transmits output signals compared with an expected value in order to verify the channel correct operation. Simultaneously, the other channel produces an output signal. Afterwards, the multiplexer (20) switches a control signal (22).
