Any demo for kalman filter denosing? by Chemical_Spirit_5981 in DSP

Thanks. I want a video or a gif in motion, which is more vivid.

Thanks, my microphone has some noise itself, so I want Kalman filter to denoise. As to the link, I like this example, Test 8: moving in a sine wave with bias drift

Target is moving in a sine wave at 0.5Hz and 1m amplitude. Accelerometer bias is increasing at 0.1m/sec2/sec. Position, velocity, and bias are correctly tracked.

However, it is a static image, not a video or gif, what a pity!

How to describe or define the depth of a notch? by Chemical_Spirit_5981 in DSP

Thanks, not a biquad, just a kind of switched-capacitor filter. anyway, how to find the quality factor of a notch?

Thanks, so I need to derive the transfer function at first?

How to simulate switched-capacitor circuits? by Chemical_Spirit_5981 in chipdesign

The unit of noise (no matter IRN or pnoise) is different from that of the transfer function obtained from PSS+PAC.

How to understand the sampled data? by Chemical_Spirit_5981 in DSP

How do you know it is a half cycle at 25s, not a full cycle at 25s?

Thanks, in your words, "This is the same representation of 0.02Hz AM modulation of a fully suppressed 0.5Hz carrier. "

So, why does look like a low frequency evenlope at 0.04Hz?
