The control effect of various intelligent terminals is affected by the data sensing precision. The filtering method has been the typical soft computing method used to promote the sensing level. Due to the difficult recognition of the practical system and the empirical parameter estimation in the traditional Kalman filter. a neuron-based Kalman filter was proposed in the paper. https://www.roneverhart.com/AMS-Neve-1073SPX-Single-Preamp-and-EQ-p33827/
