# Electronic – How to estimate the analog bandwidth

bandwidthoperational-amplifier

I have created the low cost oscilloscope and need to estimate the analog bandwidth.

I do not have any specialized equipment and just trying to estimate it by watching the response to the square signal.

Here is the 0.5MHz square wave signal:

I think I can estimate is as 6-8MHz. Am I right?

$$BW ≈ 0.35 / t_R$$
