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 ...

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 JeffreyRSmith@aol.com.

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.
