Interpreting Coherence on the FFT Analyzer

When we make the transition from the simplistic renderings of one-dimensional acoustical analysis, i.e: those that present amplitude only, we have several new traces to contend with. The most notable are phase and coherence. Phase is often minimally grasped and coherence even less so. These are both difficult because we don’t have simple mechanisms in […]

The second edition came off the press in October of this year and I am quite happy with the result. First thing is that the book can sit on your lap or a table without flopping around. The graphics came out much better. I was able to get them reformatted so as to get the most […]
