Dear Sir, I found a problem on the figure of AM (Amplitude Modulation) signal. Red curve and green curve lines are expressed as audio signal in the figure. Red curve should be written as SIN function line on the area that located on greater than or equal 0[V]. And Green curve should be written as SIN function line on the area that located on less than or equal 0[V]. When we see the red curve and the green curve from vertical direction view, they should be written as symmetric curves. Current red/green curves are crossing 0[V] line, but they ride on base line 0[V] in actual AM signal. --Dougen2015 (talk) 04:34, 29 August 2015 (UTC)
