A method of monitoring a condition of a system, the method comprising: receiving a first sampled signal having a first plurality of sampled points that originated from a sensing signal output by a process of sensing a component of a system over a dimension, the first sampled signal being sampled at a first time at a first sampling rate, and each first sampled point having an associated measured value that corresponds to a dimension value; receiving a second sampled signal having a second plurality of sampled points that originated from the sensing signal and was sampled at a second time different than the first time at a second sampling rate that is different from the first sampling rate, the second sampled points each having an associated measured value that corresponds to a dimension value; 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 plurality of sampled points and each of the second plurality of 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. receiving a first sampled signal having a first plurality of sampled points that originated from a sensing signal output by a process of sensing a component of a system over a dimension, the first sampled signal being sampled at a first time at a first sampling rate, and each first sampled point having an associated measured value that corresponds to a dimension value; receiving a second sampled signal having a second plurality of sampled points that originated from the sensing signal and was sampled at a second time different than the first time at a second sampling rate that is different from the first sampling rate, the second sampled points each having an associated measured value that corresponds to a dimension value; 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 plurality of sampled points and each of the second plurality of 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.
