Briefly, according to some embodiments of the invention a method and apparatus to generate a filter are provided. The apparatus may include a phase modulation unit to vary a phase component of a signal, a measurement unit to measure a parameter of the phase modulation unit and a filter generator to generate a filter based on the parameter. In some embodiments of the invention, the filter is adapted to provide a compensated signal to the phase modulation unit to compensate for deviation of the parameter.
