Design and Implementation of Electronic process Panel in Manufacturing EnterprisesPrefaceIn the traditional production line process, the process is designed by means of equipment tools and posted to the specific Assembly positions after the specific review process. In this way, it is competent to assemble a single and slightly changed assembly line. However, in some cases. We have to face the following prob

1. Positive Feedback and negative feedback of the amplifier.
In circuit design, the negative feedback is drawn into positive feedback. From the derivation of the principle formula, the results should be the same, but the measurement process will find that, the output end of positive feedback is always from 11 ~ Between 12 V (the power supply voltage of the amplifier is +-12 V). This is because the input and

the original must be built, and flight tests must be carried out to verify the expectations in the design.
For most people, there is obviously no project as strict as the hardware design. However, if we regard the source code as a design, we will find that software engineers have actually done a lot of verification an

secondary If bandwidth, output DC elimination, and gain can be automatically optimized during the receiving process.
DC cancellation is mainly for the receiver's second-intermediate frequency converter offset drift and phase drift to form a Low-Frequency Impedance band. It can be adjusted through the point balance between the zero and the two sides in the statistical sample set.
Gain affects the receiving effect by quantizing the position of the step. After the reference inheritance settings o

a try attitude: it is not feasible to change it, but it is not feasible to try again ...... It is a kind of "try" attitude, without focusing on the principles of theoretical methods, and often feels chaotic.
Because of its electronic background, I have learned C ++ and data structures in a simple way. More problems should be caused by the lack of ideas.
So I deeply felt that I was too bad in this regard. I felt that I should take a look at the iss

In electronic media, the concept of linear "next" is unreasonable. Readers are more likely to choose from a menu of interrelated items and decide what to look for next.

Borland China also had offer at the time, but I chose the architect role between consultants, software engineers and architects because I was more interested in this role. My current work is mainly about the architecture, design, and implementation of Shanda software platform. A
