So, neither I or my friends know anything about what kind of circuit we will be asked to build. Also, I found out that the gain value at the low and high cut off frequencies should equal to Av(max)/sqrt(2) or 0.707*Av(max), that's what the dividing by sqrt(2) was about. | |

| Jan 11, 2022 at 10:30 | comment | added | Kalamakra | So, I should be trying frequencies until Vout/Vin starts to settle to a certain value. Also, could you explain dividing by sqrt(2) and distortion at the output. Thank you for commenting. | |

The problem is I do not know which values of frequencies I should be testing, or at which frequency value I should know that the gain does not change. - this is where you test it and find out. OK, a pro would be able to estimate where these points in the spectrum are but, given that it's an experiment, you should try it at different frequencies and discover those points.
