The Interferometer Equation II David Woody OVRO, Caltech This memo repeats the content of The Interferometer Equation from Oct. 2001 and extends it to cover the explicit cases for OVRO and CARMA. This math required to determine the effects of lobe rotation and delay on double down conversion of double sideband receivers is presented. It follows the approach given in TMS on page 152 (page 178 in the new edition).
