ABSTRACT:
A method and apparatus for generating a reflection filter. The method comprises the steps of determining an averaged step response of an acquired signal and generating a spectrum response from the averaged step response. A time at which a reflection in the averaged step response begins is determined and information in the averaged step response after the determined time when the reflection begins is replaced with an ideal flat line response to generate a required step response. A spectrum response is generated from the required step response and each frequency point of the spectrum response corresponding to the required step response is divided by each frequency point of the spectrum response corresponding to the averaged step response to generate a spectrum of the reflection filter. The result of the dividing step is processed to generate a reflection filter impulse response.
