An approach to designing fault-tolerant linear analog system based on checksum-coded state-space representations of these systems is described. It is assumed that under fault, the values of the resistors and capacitors of the analog circuits are different from their fault-free values. Some shorts and opens and faults in the operational amplifiers are corrected as long as the faulty circuit behaves as a linear system. The hardware overhead is virtually constant irrespective of the circuit size
