概述
前置放大器在放大有用信号的同时也将噪声放大,低噪声前置放大器就是使电路的噪声系数达到较小值的前置放大器。
对于微弱信号检测仪器或设备,前置放大器是引入噪声的主要部件之一。
整个检测系统的噪声系数主要取决于前置放大器的噪声系数。仪器可检测的较小信号也主要取决于前置放大器的噪声。
前置放大器一般都是直接与检测信号的传感器相连接,只有在放大器的较佳源电阻等于信号源输出电阻的情况下,才能使电路的噪声系数较小。 [1]
前置放大器的作用
1提高系统的信噪比(前放紧靠探测器,传输线短,分布电容Cs减小,提高了信噪比)2.减少外界干扰的相对影响(信号经前放初步放大.)3.合理布局,便于调节与使用(前放为非调节式,主放放大调节倍数、成形常数)4.实现阻抗转换和匹配(前放设计为高输入阻抗,低输出阻抗) [2]
分类
电压灵敏前放(电压放大器)
电荷灵敏前放(带有电容负反馈的电流积分器)输出增益稳定、噪声低、性能良好
电流灵敏前放(电流前放,并联反馈电流放大器)
快响应,可获得时间信息。可远距离传输。输出脉冲上升时间和宽度窄,适合高计数率测量。
功能
前置放大器功能有两个:一是要选择所需要的音源信号,并

放大到额定电平;二是要进行各种音质控制,以美化声音。
组成
前置放大器的基本组成有:音源选择、输入放大和音质控制等电路。
作用
音源选择电路的作用是选择所需的音源信号送入后级,
前置放大器说明
同时关闭其他音源通道。
输入放大器的作用是将音源信号放大到额定电平,通常是1V左右。
音质控制的作用是使音响系统的频率特性可以控制,以达到高保真的音质;或者根据聆听者的爱好,修饰与美化声音。
功率放大器、线路放大器和前置放大器的区别和应用
是由前置放大器放大输入的信号,比如通过麦克风拾取的声音信号,由于它比较弱,需要先被放大到一定的电平才可以到其它级上。通常前置具有较高的电压增益,可以将小信号放大到标准电平上。
线路放大器是为了传输使用的,为了减小输送衰减,使接收方得到足够强的信号,输送时要进行电流放大和推动,有时也需要提高电压输送,比如定压广播就是利用这个原理的。
功率放大器主要是放大电流,这样才能推动低阻的扬声器发出声音。当然,这个例子是按音频实例讲的,若是射频信号,和这个讲法会有些出入,但是意思差不多,像发射机的功放,输出是输出到天线上的。

安装附件
在安装过程中以及安装后必须定期对传感器系统的正确运行进行校验,校验方法是移动传感器系统以模拟凸缘的运动。这种方法需要通过安装支架使传感器系统相对于轴转子和凸缘滑动。

前置器中高频振荡电流通过延伸电缆流入探头线圈,在探头头部的线圈中产生交变的磁场。当被测金属体靠近这一磁场,则在此金属表面产生感应电流,与此同时该电涡流场也产生一个方向与头部线圈方向相反的交变磁场,由于其反作用,使头部线圈高频电流的幅度和相位得到改变(线圈的有效阻抗),这一变化与金属体磁导率、电导率、线圈的几何形状、几何尺寸、电流频率以及头部线圈到金属导体表面的距离等参数有关。通常假定金属导体材质均匀且性能是线性和各项同性,则线圈和金属导体系统的物理性质可由金属导体的电导率б、磁导率ξ、尺寸因子τ、头部体线圈与金属导体表面的距离D、电流强度I和频率ω参数来描述。
