bessel filter meaning in English
贝塞尔滤波器
Examples
- State feedback greatly suit pole placement . getting optimized eigenvalue of det [ si - ( a - bk ) ] = 0 is the target of pole placement by selecting state feedback matrix k . the root of state feedback can be placed in term of the form of butterworth filter or bessel filter
极点配置就是选择状态反馈矩阵k ，使系统的本征多项式det [ si - ( a - bk ) ] = 0的本征值处于最适宜的数值上，即获得最优的根配置。 - We propose a chaos - based generation of the random ppm - ps signals , design and implement a generator of the ppm - ps signals . we introduce an if sampling technique and simulate the performances of digital demodulation techniques of using hilbert filters , sine filters , bessel filters and poly - phase filters . the poly - phase filtering method can achieve the higher mirror - frequency rejection ratio by using the low order filters
介绍了中频采样技术，并对希尔伯特滤波法、辛格内插函数修正、贝赛尔函数插值法及多相滤波法等数字解调算法进行了计算机仿真和性能比较，指出多相滤波法能以较低的阶数实现较高的镜频抑制比。 - In the seventh chapter , some of the above proposed new circuit , such as high frequency , high definition 12 - bit , 80mhz samples / s current - steering dac and fully differential r - mosfet - c bessel filter with accurate group delay , high accuracy bandgap reference and high drive capability cmos operational amplifier have been applied in communication gsm baseband i / o port integrated circuit , all the above blocks meet well with the design requirements of the system , and gain the better testing results , in the mean time , the above proposed high accuracy bandgap reference circuit als
