Abstract:
1. A signal processing device comprising a first processing apparatus having a first processing apparatus output and a second processing apparatus having a second processing apparatus output: the first processing apparatus configured to perform a first process on an input signal set independent of the second processing apparatus to generate a first processing apparatus output signal, wherein the input signal set comprises one or more input signals; the second processing apparatus configured to perform the first process on the input signal set independent of the first processing apparatus to generate a second processing apparatus output signal; wherein a first processing apparatus failure signal is provided at the first processing apparatus output when the first processing apparatus fails integrity testing; further wherein the first processing apparatus output signal is provided at the first processing apparatus output when the first processing apparatus passes integrity testing; further wherein a second processing apparatus failure signal is provided at the second processing apparatus output when the second processing apparatus fails integrity testing; further wherein the second processing apparatus output signal is provided at the second processing apparatus output when the second processing apparatus passes integrity testing; wherein the first processing apparatus output and the second processing apparatus output are independent and are configured to provide processing apparatus output signals to be combined to generate a signal processing device output signal.
