ABSTRACT:
Non-multiple delay element values that may be implemented to reduce periodic quantization errors associated with phase shifting devices used in phased array apparatus. The non-multiple delay element values may be implemented so that a magnitude of phase shift imparted by a given delay element of a phase shifting scheme is not a multiple or a factor of the magnitude of the phase shift imparted by any other delay element employed in the same phase shifting scheme.
