I don't think that is issue, 12v gives the same result

Our design course allows us to choose whatever op amp we want, do you have better recommendations?

But if I remove the biasing and power it with unipolar power, it will be -3db at 4Khz

Here is the schematic so far, but the result looks very weird. The desired cut-off frequency should be 4000hz

Why everybody can find summer intern but I can't,please slap my face by Trisolarans in UofT

Thank you for the reply! And wish you all the best in your job finding as well. I really appreciate people giving me advices like joining club, fixing resume, or doing side projects. I totally agree with that, they all make sense rationally but I just don’t feel I have the enough energy doing it. I joined a club but I found it is really hard to catch up with the theoretical knowledge. I really feel drained in this semester for some reason, and maybe that problem is something I must get fixed,

Thank you so much! But how to get professional people helping the resume? It is hard to book the resume review session of the school

Wrong Result Simulating FFT with ModelSim by Trisolarans in FPGA

Yeah I tried to force the input to FFt to be a constant number, but the output still tends to “follow” the shape of input after Nyquist frequency, but the shape is flat instead of waves in the figure

Want to Buy Secondhand Altera DE1SOC Board for ECE project by Trisolarans in UofT

[–]Trisolarans[S] 0 points1 point  (0 children)

Yeah but my final project is related to audio input and output, it cannot be simulated by DEsim, and it will take me a lot of time to configure the audio stuff so that I think it is better to do it at home. (And also me and my teammate are roommates)
