Help with Circuit to Invert Graph

[vk6kro]

He is on medicines thanks for asking
Can u draw a circuit actually i m having exam
i am a student of computer science and i am into 3d designing so i don't know about electronics much
Draw a circuit for me and i will try to make a circuit like and will make a video if i do something wrong u will see it in the video
O.K
SO u can guide me
Can u please?

You don't know about Electronics but you are doing an exam in it? That is amazing.

Anyway, here is a high pass filter:

Can you see how it works?
The capacitor has less and less reactance as the frequency rises, so it drops less of the input voltage and more gets to the output.

I'm not sure anymore but I think he was wanting a op-amp circuit. Think you'll be able to explain it before the exam?

 

[vk6kro]

No problem. :)

I was wondering if some Butterworth filter pole-zero diagrams might cheer his friend up a bit and speed his recovery?

lol u are funny
So u gona show me a circuit diagram?

 

[vk6kro]

Which circuit are you looking for?

 

[sheheryarnoor]

The circuit which can make a graph on Vout like the one in the pic

This circuit will give that spectral response if the signal generator at the left is set to give 2 volts peak.

Look at this video i made a circuit like this but it didn't give me the desired graph

I'll give you the answer if you tell me what the cut-off frequency of the filter is.

I don't know because it isn't my project i am doing it for my friend i don't know about electronics and i am learning from this site little i got that what is HPF and LPF and actually he just needs a graph like the one i have displayed in the pic
Anyone can make a circuit for it to get a graph like this?

 

[sheheryarnoor]

So anyone gona help me?
Please

What would you like to know?

When you do a simulation, do a screen grab of the graph and also the circuit you have entered.

A 10 MB video is too big to download.

To do a screen grab, push the PrtSc key (next to F12) and paste into MS Paint.
Trim off the menu bar and any other unnecessary stuff and attach it to a posting.

I would turn off bias point detail and increase the upper frequency to 1000000 Hz, not 1000 Hz.

Try that.
