Webigppweb.ucsd.edu WebIt is possible to unwrap the phase and determine the absolute time delay associated with it if the phase variation is assumed to be continuous with frequency, if that variation is sufficiently resolved in 〈θ ab 〉, and if the phase is defined continuously down to a frequency where the time delay is less than half the period. In that case we will be able to …
