Recently, the fixed-pole design of second-order parallel filters has been introduced to accomplish arbitrary (e.g., logarithmic) frequency resolution for transfer function modeling and equalization.

In the logarithmic detection mode, LOGOUT pin is externallyconnected to the VSET input pin (closing the feedback of the output buffer) resulting in a nominal logarithmic slope of 19 mV/dB and an ...

Abstract: In this paper we propose a new speech enhancement based on the sparse representation in logarithmic frequency scale. The proposed method creates the dictionary from the spectrum in ...
