Abstract

A combined adaptive up-and-down method for comparator type equivalent time transformation is proposed. The method uses the signal increment at the preceding phase point of the signal as well as the data for the current signal phase. The efficiency of the proposed method is compared to those of other comparator type equivalent time methods. The method is investigated for implementation in UWB radars.
