Abstract
A paradox arises in a paper by Kuo and Vijayan (see ibid., vol.5, p.374-7, 1997) because notching out narrowband primary noise would seem to also prevent secondary path identification at the primary center frequency. This conundrum is resolved by examining the notch bandwidth in comparison to the resolution of the model filter
