Query: IWAVE -- An Adaptive Filter Approach to Phase Lock and the Dynamic
  Characterisation of Pseudo-Harmonic Waves   We present a novel adaptive filtering approach to the dynamic
characterisation of waves of varying frequency and amplitude embedded in
arbitrary noise backgrounds. This method, known as IWAVE, possesses critical
advantages over conventional techniques making it a useful new tool in the
dynamic characterisation of a wide range of data containing embedded
oscillating signals. After a review of existing techniques, we present the
IWAVE algorithm, derive its key characteristics, and provide tests of its
performance using simulated and real world data.
