Enter the Spectrum Analyzer; In this case it’s some math that occurs in my Digital ... listening carefully one can start to equate sine wave distortions with “spray” or the extra harmonics ...

In general, a good math model for a sine wave is: y=A*sin(ωt+Φ) Let’s dissect what this equation to see what it’s all about. The sine angle is in radians and ω is the frequency in radians.

The sine wave has a period of Τ = 2π and an amplitude ... Jeff Smith is a former Math teacher and a retired US Navy Lieutenant Commander. Reach him at [email protected].
