time z

SAW-based real time chirp z transformation processor is widely accepted as one of new supporting techniques for spectrum analysis in radar, communication, electronic warfare and radio telescope.

基于线性调频变换算法的SAW富氏谱分析技术是现代雷达、通讯、电子对抗及射电天文等领域的新一代支持技术之一。

In this paper, a model for read/ write head is presented at first, i. e., the standard state space system of observability, and then, the continuous-time state-space is converted to discrete time G ( z) by means of Tustin method.

本文首先建立了磁头定位系统的数学模型&能观的状态标准型，然后用Tustin法求得了离散化的Z变换传递函数。

Depending on the initial load inductance and the implosion time, PBFA Z has attained peak currents of 16-20 MA with a rise time of 105 ns.

在一定的负载条件下，得到了上升时间为105ns，峰值为20MA的电流脉冲。

Assume z axis vertically downwards, and take ground as grid origin. Q ( z, t) is the water-bearing rate at t time in z under ground.

设z轴垂直向下，坐标原点取为地面，Q（z，f）为在t时刻离地面距离为z处的土壤含水率。
