Hello.
I have an audio signal (i.e 100Hz / 5Volts peaktopeak) that passes through a peak rectifier.
The resulted signal is the red line on the schematic below.
As u can see, the signal follows a relationship F(t) over time.
What I want is to be able to calculate the surface area "A", with analog electronics.
Maybe the math included in the graph could help..As u can see, area "A" in the integration of F(t) for the time period between t1 and t2.
My main concern is to calculate "A" and output a DC voltage in relation to how big this surface area is..Got it??
Hope somebody could help.
Thanks in advance,
xmat.
