Hi, I need to to the following exercise:

Question

Estimate the measured rise time when connecting a 10kHz square signal, with an output impedance of 1 kΩ, to the oscilloscope using a coaxial cable.

I know that Rise time = 0.35/BW, but I don't know how can I find the Bandwidth of a square signal when it is supposed to be infinite.

Thanks!

Answer 1

The bandwidth is the bandwidth of the oscilloscope's front end. Since you are estimating, use 10Mhz.

Answer 2

Thanks!
