A method of monitoring a condition of a system is provided. The method includes receiving a first sampled signal having first sampled points sampled at a first sampling rate, and receiving a second sampled signal having second sampled points sampled at a second sampling rate. Both the first and second sampled signals originate from sensing over a dimension in the same sensing process. The method further includes determining a first shift over the dimension between the first sampled signal and the second sampled signal at a first sampled point of the first sampled signal, determining a second shift over the dimension between the first sampled signal and the second sampled signal at a second sampled point of the first sampled signal, the second sampled point being different than the first sampled point, determining a calculated shift that is a function of the first shift and the second shift, generating a merged signal that includes each of the first sampled points and each of the second sampled points shifted based on the calculated shift, determining whether there is at least a threshold indication of failure based on analysis of the merged signal, and disabling or recommending for removal the component in response to determining that there is at least a threshold indication of failure.
