输入调节和输出调节单元之间的差异

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，电压放大或电压水平可能会发生变化。为了满足有关电信号的级别和此类属性，需要进行不同的调节。

系统中主要有两个调节单元：

1.输入调节单元：
输入调节单元是一种调节器，用于改变来自传感器/环境并进入系统输入接口单元的电信号的特性。可能会有问题，例如输入电信号的电压在毫伏范围内，而系统仅接受伏特范围。在这种情况下，使用输入调节单元。

2.输出调节单元：
输出调节单元是一种调节，它会改变来自系统并进入环境/执行器的电信号的特性。可能存在诸如输出电信号的频率范围不符合执行器比例之类的问题。在这种情况下，使用输出调节单元。

输入和输出调节单元之间的差异：

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.
