尖锐的采样信号很难获得,因此,这两次滤波(Sa函数和理想低通)可以合并(级联),并且由于这各系统的滤波特性是物理不可实现的,所以在真实的系统中只能近似完成。
2. 模数转换器是将模拟信号转换成数字信号的系统,是一个滤波、采样保持和编码的过程。
模拟信号经带限滤波,采样保持电路,变为阶梯形状信号,然后通过编码器, 使得阶梯状信号中的各个电平变为二进制码。

车间电网防雷效果不好,强烈雷击会造成电网不稳定,容易发生晶闸管模块击穿、熔断器烧坏现象,这在大功率直流调速器上表现的尤为严重。因此供电电网的稳定是直流调速稳定运行的基础条件,若遇到强烈雷雨天气或电网不稳定时,好暂时停止使用设备,待电网稳定后再重新投入使用。
由于压力机的启动为重载启动,因此,电机不能频繁启动,次数限制在每小时不超过4次为宜,机床断电时,停主电机,等主电机停稳后,再切断电源。
