QUARTER WAVELENGTH UNIT DELAY AND COMPLEX WEIGHTING COEFFICIENT CONTINUOUS-TIME FILTERS

Various signal processing techniques may benefit from appropriate handling. For example, certain signal processors may benefit from quarter wavelength unit delay and complex weight coefficient continuous-time filters. A method can include splitting an input signal into a plurality of signal paths. The method can also include complex weighting, for each signal path, a respective signal. The method can further include summing outputs of the signal paths. The method can additionally include providing an output comprising the sum of the signal paths. The complex weighting can be configured to independently control gain, phase and delay of the output signal over broadband.
