A computer program, NASAP (Network Analysis for Systems Applications Program), has been adapted to perform fault diagnosis in frequency-dependent systems. The program simulates a short circuit and an open circuit for each network parameter and prints out a modified transfer function of the network corresponding to each simulated failure. Experimental and simulated data are subjected to correlation and variance analysis in order to rank all parameters according to probability of failure in the network model. The program lists, at present, single failures in order to decreasing probability. Possible extensions of the program to multiple failures are examined.
