Analytic signal generation-tips and traps

  title={Analytic signal generation-tips and traps},
  author={Andrew Reilly and Gordon Frazer and Boualem Boashash},
  journal={IEEE Trans. Signal Processing},
In this correspbndence we discuss methods to produce the discrete analytic signal from a discrete real-valued signal. Such an analytic signal is complex and contains only positive frequencies. Its projection onto the real axis is the same as the original signal. Our use stems from instantaneous-frequency estimation and time-frequency signal analysis problems. For these problems the negative frequency component of real signals causes unwanted interference. The task of designing a filter to… CONTINUE READING
