The Model 90 low pressure and Model 91 high pressure Selector Relays are designed to select the lower or higher of two signal pressures to provide a continuous output pressure to a control device.
In practice complex alternating projection neural networks can be widely applied to signal processing, such as band-limited signal extrapolation, frequency selector and trap filter.
实际上，复交替投影神经网络不仅可用于信号处理中的带限信号外推，还可用于选频、陷波等场合。
