Click For Summary
The discussion revolves around a request for help with a technical question related to electrical engineering, specifically involving RC low pass filters and their frequency response. The original poster did not provide sufficient details about their problem or previous attempts, leading to confusion among responders. Participants emphasize the importance of clearly stating the issue and providing context rather than linking to inaccessible images. The poster clarifies that the question pertains to a past paper from City & Guilds and seeks assistance with calculating dB gain and understanding roll-off in dB/octave. The conversation highlights the need for clear communication in technical inquiries to facilitate effective assistance.

Stop.

You posted the first request at 9:38 AM. You have to give people a chance to respond.

Your original post does not specify what you want help with, what your problem is, or what work you have done. It instead links to images that I cannot see unless I register at some other site. Sorry, that ain't going to happen.
 


I think now u can see

Im sorry about that.
now its ok.
pls help me.
 


A moderator still has to approve the images, why not just write out the problem and what you've attempted so far?
 


1. sketch a cct diagram of a single pole RC low pass filter with R=1k & c=4.7microf
2. The amplitude response of the filter in 1 given by,

|Vo/Vin|=1/√(1+(ω/ωo)^2)

a . where ωo is the cut off frequency.by considering a number of frequency regions, sketch a freqency response (Bode diagram) of the filter ,labelling the relevant parameters.

b. calculate the dB gain at 2ωo & 3ωo & state the value of the slope of the role-off in dB/octave.

3. sketch LRC band pass & band stop fiter ccts


other q has a diagram
how find small signal 3dB upper frequncy usin transfer funtion of low pass active filter
 


What have you done so far? We are you to help you do your own homework. We do not do your homework for you.

That is not homework this is past paper question of City & Guilds advance diploma. i can't understand what is the role-off in dB/octave & how fined dB gain at 2ωo & 3ωo using transfer funtion.

Ru konw how fined those?
