Abstract
There is described a two-channel method for determining at least one output signal from variable input signals sent by a transmitter, using two independent channels and consisting in alternately guiding the input signals to said channels, wherein a multiplexer is used for switching said channels. A microprocessor 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 switches a control signal.
