slow-down signal

Most people hide their routers because they're unsightly or in the way, but placing a router in a closet is a one-way ticket to slow Wi-Fi: Walls and doors can degrade and absorb signal strength.

多数人会嫌路由器有碍观瞻，或因挡道占地方而把路由器藏起来，但把路由器放橱柜里只会减弱Wi-Fi信号：墙壁和门会吸收信号、降低信号强度。

The results of analysis show that: the average probability of error for digital data communication in slow Rayleigh fading channel is less one half magnitude than the optimized threshold detection with fading signal at same mean SNR.

结果表明，在Rayleigh慢衰落信道上采用这种检测器，相对于工作此信道上的最佳固定门限检测器，在不同输入信噪比情况下，其平均误码率约有半个数量级的改善。

The NN slow subsystem keeps the control signal from being saturated.

神经网络缓慢子系统防止控制信号被饱和.

If fatigue damage of the bearing develops at a slow rate, the stationary vibration signal, i.e., an ergodic process, would result.

如果轴承的疲劳发展缓慢，振动输出稳态信号，也即表征各态经历的过程。
