mmm... i disagree. fault tolerance is more of a reliability property that sits outside of the performance of a discrete logic or signal processing system, it describes how well a system can remain functioning in the face of adverse conditions like internal failures, hardware substrate failures, dependency failures, adverse inputs, etc. but... yeah, some problems have continuous performance variables (typically ee'ish) and others have discrete ones (typically cs'ish). the discrete account ledger either computes the correct value or it does not, where many signal processing problems have to contend with noise and are allowed to produce a wide range of noisy outputs and therefore their measures of correctness are based on statistical arguments.
