Abstract
The invention may provide a method and filter block for compensating droop in a frequency response of a signal. The filter block may include a decimator, which decimates a high frequency input signal to a set frequency output signal. The set frequency can be, for example, the Nyquist frequency for the input signal. Further, the filter block may include a droop compensator that compensates the droop in the frequency response of the output signal from the decimator. The droop compensator may be made using recursive filters, as opposed to large tap FIR filters, which may result in less memory consumption and decreased power consumption.
