The slew rate is the rate of change of the output voltage variable, often defined as volts per second (or microseconds). 8. Noise figure is a metric for how much noise the amplification process introduces. In electrical devices and components, noise is unpleasant yet unavoidable. With zero in...
Displacement: A linear variable displacement transducer, or LVDT, is an electrical transducer used in measuring linear position. Linear displacement is the movement of an object in one direction along a single axis. Measuring displacement indicates the direction of motion. The output signal of the li...

This simple amplifier is known as 'single-ended, Class A'. It has only one output device, and when there is no signal the current through the output transistor is at least as great or greater than the maximum current that ever flows through the loudspeaker. So the Class-A amplifier is ...
GA is used to determine membership function especially designed in situations. We use GA to tune of the membership function for terms of each fuzzy variable. 一种新的方法为使用GA的模糊控制器排程序合理化。 GA用于确定在情况特别是设计的会员资格作用。 我们使用GA到会员资格作用的声调为每模糊的可变物...
Reverse Isolation is a measure of the ability of an RF amplifier to prevent signals from leaking or coupling back into its input port from its output port. In simpler ter
