To the best of our knowledge there exists no algorithm so far in the literature either in time or frequency domain that performs lowpass highpass bandpass and bandstop filtering of the input auto and cross correlation sequences through
This filter has a single passband property because of the lowpass characteristic of the DGS and highpass characteristic of the interdigital coupling line.
