🌟 nau8825_xtalk_sidetone(9) 🌟

okay so welcome to the Kernel API Manual, bestie — today’s main character is literally nau8825_xtalk_sidetone, and she’s here to compute cross talk suppression sidetone gain. no cap. 💅

---

🎀 NAME 🎀

nau8825_xtalk_sidetone — computes cross talk suppression sidetone gain. periodt.

---

✨ SYNOPSIS ✨

u32 nau8825_xtalk_sidetone (u32 sig_org , u32 sig_cros );

---

🫶 ARGUMENTS 🫶

• sig_org — the orignal signal level. yes bestie, that’s what it says 👀
• sig_cros — the cross talk signal level.

---

💖 DESCRIPTION 💖

The orignal and cross talk signal vlues need to be characterized. like, that’s the vibe check they have to pass first, okay?

Once these values have been characterized, this sidetone value can be converted to decibel with the equation below:

sidetone = 20 * log
(original signal level / crosstalk signal level)

Then it’s giving: return cross talk sidetone gain. slay. 💫
