左分解 meaning in Chinese

left resolution
left sided decomposition

The exact design methods of switched - current filters are summarized , such as the director synthesis of z - plane , euler mapping , state variable analysis , matrix decomposition , and signal - flow - graph simulation of the lc and switched capacitor prototypes . at the same time , a modified left decomposition matrix method is proposed to overcome the usual problems of large silicon area , high sensitivity and component spreads by minimizing the input circuits . examples of switched - current low - pass , high - pass and band - pass filters are given to verify the feasibility of these methods
总结分析了实现高精度开关电流滤波器设计的各种实用方法，包括z域综合法、欧拉映射法、模拟无源lc网络和开关电容网络的状态变量法、矩阵分解法和信号流图转置法，并对左分解法加以整理改进，提出一种更为简洁的设计结构，通过减化输入电路克服一般电路中存在的占用硅片面积大、灵敏度高等问题。
