With regard to the harmonic waves also, the PWM converter 4' works so that the AC filter 6 more absorbs the harmonic current of a load 7 and the PWM converter 4 works so that the harmonic voltage of the power supply system is not applied to the receiving point. That is, the harmonic...
The active methods require more sensors and increase algorithm complexity, while additional damping resistors are needed in the passive methods and result in large losses. Simulation validates the feasibility of the method proposed by this paper. 展开 关键词: Active damping Active power filter LCL-...
If you own a diesel car, then you need to know about active and passive diesel particulate filter regeneration. In diesel cars, the DPF captures and stores exhaust soot to reduce the levels of harmful emissions produced. For your DPF to run as it should, it goes through a process ...

Generally speaking you can only get boosted levels from an active device. But there is at least one system, by Villex, that claims to be able to boost the signal passively. The only way it is able to do this is by tuning a resonant filter to rob energy from the frequency ranges that...

2.A condition and design method was obtained,under which the filter made the corresponding expanded system passivity.利用构造Lyapunov函数的方法研究了一类中立型不确定线性系统的滤波器设计问题,得到了使相应增广系统是无源系统的滤波器存在的条件和设计方法,并且将结果化成线性矩阵不等式的形式,容易求解,最后用一...
This allows an additional 15dB of IF filter loss, while still enabling the receiver to meet sensitivity and spurious-free dynamic range requirements. Figure 1. LTC554x passive mixer in a receiver application. Active Versus Passive Mixers Most integrated-circuit mixers are based on an active or ...
The last item on the line is optional if you want to filter the packets based on packet type (for example, TCP). To take further advantage of Snort's packet logging features, you can use Snort in conjunction with the Berkeley Packet Filter (BPF). ...
Because of a wide range of input impedance possible, stubs are widely used as impedance transformers and matching networks, as tuning elements or dc-bias networks (a kind of low-pass filter), and as baluns or filters. The most commonly used load conditions of a stub are either a short ...
