should correspond to the things, actions, and their relationships in the real world. What are the things in the real world, what actions should these things have, and what is the relationship between them, in the software world, we should design classes, methods, and associations between them. Only such a design is the most understandable
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

At present, goods after-sales repairs are still chaotic in China, and there are no standards to follow. Therefore, after-sales repair software is even more complicated and there is nothing to learn from. Many development companies
Six principles of design patterns (5)-the six principles of design patterns
Definition:
An object should have a minimum understanding of other objects. The dimit rule is also known as the minimum Knowledge rule. It is called the Least Knowledge Principle (LKP) in English.
Personal Understanding:
The primary objective of the dimit rule is inter-class decoupling
project team develops to 5-10, the testing work in the project must be completed by dedicated testers. Generally, four to six developers need to configure a dedicated tester. Testers conduct system tests from the perspective of third parties and simulated users to better discover system bugs and problems and effectively ensure the quality of the system.

The graphic analysis model is an excellent supplementary description of the Software Requirement Specification. They provide different information and relationships to help locate incorrect, inconsistent, missing, and redundant requirement

All of these are the most critical factors that affect functional requirements. Functional requirements are also the first and most important factors that affect the design specification book to clearly describe and solve.

U disk must have 5 software
I believe you have more than one of the hands of a U disk. So, what can you do with your USB flash drive in addition to storing files? I'm afraid this is a problem that many friends often think about. So today, I would like to introduce you to a few small software, let them to help you "play turn" in the hand of the U disk Bar.

Template Method pattern (JAVA) of software design pattern, design pattern java
What is the template method mode?
Defines the skeleton of an algorithm in an operation and delays these steps to the subclass. The template method allows the subclass to redefine certain steps of the Algorithm without changing the structure of an algorithm.

Ubuntu efficiency Software Overview
In a series of previous blogs, we have consolidated the basic knowledge required to use the Ubuntu system. In this article, let's talk about this low-key and powerful platform, how to enable the operator to follow the design philosophy of the system and use appropriate software to achieve a human-computer integration environmen
? In fact, you don't have to worry about where to put it. The dimit rule gives us a solution:
If a method is put in this class, that is, the relationship between classes is not added, and there is no negative impact on this class, it is placed in the class.

Serialization is used to sequence object memory data so that it can be transmitted through different media. However, if our softwa

The team mode refers to the way a team member works together, and the team's development mode is used by the software development team in the software development process. That is to say, the team development mode is a special team mode for applications in the
