Hi all, I have some questions to answer for my HNC homework, but am having a little trouble understanding the example we were given. I have top draw out some asymptotic bode diagrams. In the example given the bode diagram was derived from the following formula: Vo / Vin (jω) = 3 / (1+j3ω)(1+j4ω) I know that the break points are at 0.25 and 0.33 as these can be found by inverting the constants 3 and 4, but I am not sure how to find the start point, which in this case is 9.5dB. Any help would be much appreciated. Mark
The formula you need to apply is: The 3 used above is the voltage gain taken from the transfer function. hgmjr
