Abstract

This paper describes the design and performance of a digital filter basfd upon the FAD (Filter And Detect) integrated circuit. Although the filter was initially devised to provide economical and flexible processing for low-and medium-frequency sonar system testing, simulation and signal processing, it may also be applied to a wide range of fixed-parameter or time-variable filtering tasks in the frequency band to 40 kHz.
