Hello,
I want to ask this question stated in my textbook:
Can an low-pass RC filter be used to provide 1dB attenuation at 21 kHz and at least 22 dB attenuation at 820 kHz?
It is written in the solution that the 3 dB frequency is 41,27 kHz. I don't know where this comes from?
Can you please help m? Thank you.
