Decomposition of multi-exponential and related signals is generalized as a filtering problem on a logarithmic time or frequency scale and FIR filters operating with logarithmically sampled data are proposed to use for its implementation. The filter algorithms and types are found for various time-domain and frequencydomain mono-components. It is demonstrated that the ill-posedness in the multi-c...

In this note, stability is imposed by using regularization. The...
