By measuring the correlation of two-channel input signals, the synchronism of acquisition signals is verified.
通过对双通道采集输入信号的相关性测量，验证了采集的同步性。
The AD7745 has one capacitance input channel, while the AD7746 has two channels.
AD 7745拥有一个电容输入通道，AD 7746则拥有两个通道。
In the condition of two-channel, when input pulses overlap, the output power and gain become steeper.
在双信道情况下，输入脉冲重叠时的输出功率和增益变得更陡峭。
This example uses two analog input channels and one analog output channel.
这个例子使用2个模拟输入通道和一个模拟输出通道。
Two-channel operation: Redundancy in the input circuit. Earth faults in the Emergency Stop circuit and shorts across the emergency stop push button are also detected.
双通道操作：输入回路中存在冗余重复输入。急停回路中的接地故障及急停按钮相邻成对触点间的短路故障都将被检测。
