8. Signal Processing in Mixed Signal Systems
Signal processing serves as a critical component in mixed signal systems, where analog signals are digitized and processed using various digital techniques. Key processes include filtering, modulation, noise reduction, and control systems, which are essential in applications such as biomedical monitoring, industrial control, and wireless communication. The effective implementation of these techniques can greatly enhance system performance and data integrity.
