Design of Compensators for Comb Decimation Filters
Gordana Jovanović Doleček · IGI Global eBooks · 2017
This article presents different methods proposed to compensate for the comb pass band droop. Two main groups of methods are elaborated: Methods that require multipliers, and multiplier less methods. The width of pass band depends on the decimation factor and the decimation of the stage which follows the comb decimation stage. In that sense the compensation can be considered as a one in the wideband, or in the narrowband. There exit methods which can be used for both: wideband and narrowband compensations (with different parameters). Usually there is a trade-off between the compensator complexity and the provided quality of compensation.
