| ZipCPU | Quadratic interpolation anyone? http://zipcpu.com/dsp/2018/03/30/quadratic.html | 21:10 |
|---|---|---|
| tpb | Title: Quadratic fits are entirely inappropriate for DSP (at zipcpu.com) | 21:10 |
| shapr | yay! | 21:10 |
| ZipCPU | Thanks | 21:13 |
| ZipCPU | That post was a long time in coming. | 21:13 |
| awygle | I've never used a quadratic fit in dsp but never really thought about why lol | 21:14 |
| awygle | Never got past first order holds and similar | 21:15 |
| ZipCPU | awygle: Now, any time you have two multiplies to spare, you have no excuse not to :D | 21:18 |

| pie_ | oh god that looks horribly my eyes | 23:54 |
| pie_ | looks like an interesting article, thanks :D | 23:55 |
| awygle | yeah i was thinking that the whole time. "people DO this? but it's so obviously terrible!" | 23:56 |
| awygle | i am of the opinion that Splines Are Where It's At for >linear interpolation, i look forward to the article explaining why that's wrong :p | 23:56 |
