The waveform of the filter circuit is wrong?

Connect one end of the resistor to the output end to pin 2 to try, and then calculate the value of the ring frequency by yourself to set the capacitance parameters. You can use software to design, set the high pass and cutoff frequency and then imitate it.

Filtering is just attenuation, not completely blocked.

In addition, the leads of the oscilloscope can be in different colors, so that the color of the curve is different.

Change the color of the lead: right click on the line.

1. Your circuit is wrong;

2. The resistance and capacitance are too large;
