No phase information is used, so no ground balance or discrimination capability. The "Ground" control in the design is actually the threshold adjust. This article was published in the May 1994 issue of Silicon Chip magazine. Because of the file size of the complete article, I've included a lite version, that lacks non-critical photographs.
