cell phone jammer can be commissioned and adjusted

 cell phone jammer can be commissioned and adjusted for the customer. 
The main measures. Optical coupling isolation optical coupling to the microcontroller and to channel direct electrical contact between the cut off to prevent interference from the process channel into the microcontroller. The main advantage of optical coupling is able to effectively suppress spikes and noise interference, the process of channel SNR. Two. Twisted pair transmission in long-term transmission of applications, UTP is the more commonly used as a coaxial, although the band is poor, but high impedance, resistance to common mode noise immunity, it also enables each The small-loop electromagnetic induction interference cancel each other out, have some inhibitory effect on the electromagnetic field. The anti-jamming design of printed circuit board printed circuit board hardware systems, devices, signal lines, power lines of high-density aggregates. cell phone jammer has the most suitable and appropriate ambient temperature to turn on.
Its design must meet the the Hang interference design principles, usually printed circuit board design to solve problems include: the power supply and ground design, the signal lines to the design, component configuration. A. Power supply and ground design in the hardware system, the ground is an important method to suppress interference. The operating frequency of the system to determine a single point or multi-point connected to shield ground. Separate digital and analog circuits, to distinguish between digital ground and analog ground, connected to the ground with the power supply side, try to increase the ground area of the analog circuit to reduce the common impedance, reducing the fluctuations of the ground potential, the digital circuit of the grounding line is the best form loop. Network-like ground, to reduce the differences in ground potential. The too low or high temperature might influence the laser energy of phone jammer .This topic in the topics and the research process the teacher's guidance package Jia Qi packet teacher had the work involved, but in my graduation project at each stage, from access to information, research to determine and modify the mid-term examination. detailed marking to the late package teachers have repeatedly asked the research process, and over to help me, help me to develop research ideas, careful coaching, enthusiasm to encourage. Package style of teachers meticulous, rigorous and realistic attitude, the sense of spirit, not only granted I should like to, but also taught me life, I will be a lifetime benefit. Words can not express gratitude for package teacher.
