Frequency detection using Pade approximation

Show other versions (2)

The current paper describes an application of Pade approximation to obtain a frequency detection method similar to (and, in a sense, more general than) linear prediction. While generally not applicable for spectrum estimation, the described method is in many cases more precise in finding the freque...
