... by dividing the area into trap-ezoids, we can calculate the area of each trapezoid and sum them to calculate the total area. The area of a trapezoid is the average of the sum of the two parallel ... process for a second diagram for the astable configuration, even though we are getting a little ahead of ourselves. We create form frmAstable and insert an image control using the image astable.wmf.While ... value up. Cell E6 becomes: =INDEX(StdCap!B4:B 16, (MATCH(Cap,StdCap!B4:B 16) +1),1)Having calculated the standard capacitance, we need to reevaluate the input waveform. Cells F13 to F53 contain...
