Mobile Phone PCB Board Reverse Engineering

Nowadays, the functions of mobile phones are becoming more and more abundant which will make the Mobile Phone PCB Board Reverse Engineering becoming more complicate, and without exception, the high and low levels of their audio functions are paying more and more attention.

So its audio capabilities must also be improved while voice calls can still use mono with relatively low fidelity, music and video functions require higher sampling rates for high-quality stereo electronic PCB card reproduction.

The two audio streams are independent of each other, but since both share the same headset, speakers or microphone, they must work together seamlessly. Compared with a pure multimedia system without a voice stream, the complexity of this system with two sets of audio is greatly increased. At the same time, mobile systems are subject to the same severe constraints as other mobile phone systems in terms of printed circuit board space when reverse engineering, electrical power, CPU cycles, and component costs.

While the added footprint of integrating additional circuitry on an existing IC is relatively small, it may result in too much power dissipated or an unacceptably high added cost.
