hello guys

For school I need to do a practical tasks which involves some theoratical preparation. School gave me this problem.


For H(w) i have
I have to find out the ratio of R1 and R2 for the gain to be -12dB for example R1 =aR2 where a needs to be determined.
If someone can help me out I would be glad, also some tips for some usefull books or videos would be appreciated a lot.

ps sorry for the bad spelling English isin't my main language

 

Does It say for what frequency the gain has to be -12dB?

No the first question is what is H(jW) then it asks if it is low or high pass filter i have low pass. After that this question they dont give a frequency.

 

I agree with you on H(jω).
I agree on low pass, but that’s not the whole story.
When you first see a filter, to determine what it does, analyse it at two very easy frequencies, f=0 and f=∞.
What does that tell you about this filter, that is different from the usual low pass filter you see?
