Abstract :
Frequency-domain least-squares filter design is extended to the case that magnitude and phase are not specified for all test frequencies. Unspecified quantities are obtained by an iterative, alternating projection algorithm. Examples of gain-only and phase-only identification are provided, as well as filter design.
