输入调节和输出调节单元的区别

在将信号从用户传输到计算机系统时，反之亦然，电信号的频率范围、电压放大或电压电平可能会发生变化。为了满足有关电信号的电平和此类属性，进行了不同的调节。

系统中有两个主要的调节单元：

1. 输入调节单元：
输入调节单元是改变来自传感器/环境并进入系统输入接口单元的电信号特性的调节单元。可能存在一些问题，例如输入电信号的电压为毫伏范围，而系统仅接受伏特范围。对于这种情况，使用输入调节单元。

2. 输出调节单元：
输出调节单元是改变来自系统和进入环境/执行器的电信号特性的调节。可能存在输出电信号的频率范围与执行机构的规模不符等问题。对于这种情况，使用输出调节单元。

输入输出调节单元的区别：

INPUT CONDITIONING UNIT	OUTPUT CONDITIONING UNIT
It is used for conversion of characteristics of incoming signals.	It is used for conversion of characteristics of outgoing signals.
It takes input from sensor.	It takes input from output interface unit.
It gives output to the input interface unit.	It gives output to the actuator.
It is a mediator between sensor and input interface so that signals can be scaled.	It is a also mediator between output interface and actuator so that signals can be scaled.
It converts low range frequency signals to high range frequency signals.	It converts high range frequency signals to low range frequency signals.
Example: Conversion of signals from photo-voltaic cell from mV to V.	Example: Conversion of frequency of signals to user convenience.
