approximately constant during the demodulation process. Step 3 Update the loop intermediate variable s_pll (n ), F0 is a fixed NCO center frequency. So far, a complete SPLL computing is complete. In step 3 and Step 4 calculation, the ring filter coefficients C1 and C2 can pass the loop sampling interval T (or the loop update interval) determine the free loop frequency ω n and the damping coefficient of the loop, as shown in [2]: KD is the gain of t
feedback to the trajectory interpolation task. Graphical user interface: The above functions can be integrated into a GUI interface based on Qt. 1) Think about the development of which module you are best at or interested in, and write on your blog.2) In addition to programming, you can contribute to a software project in a variety of forms, such as team management, requirements analysis, functional definition, algorithmic
"Maze" Project Review I think this maze is a very good little game. One of the single-player game and death mode is more common, but the two-person mode is very interesting to listen to, the usual maze is a person does not mean, but joined the double-mode competition, immediately feel different.Can be in the boring time to call friends, play together, in general, is a very good idea.

Software and Hardware Design and Implementation of DSP-based Internet Access Solution [Date:] Source: Electronic Technology Application by fan Qing Han Chong Zhao Wei Hua [Font:Large Medium Small] With the development of modern network technology, embedded systems, such as single-chip microcomputer and DSP, require more and more access networks, for example, an electric meter system w
Axure RP's Widgets toolbar is the tool we use to draw a wireframe wireframe, Flow diagram, or a part that makes up our final output chart. Like when we were kids to play with the building blocks, these tools is to assemble a block of small parts, what constitutes? How was the combination? Rely entirely on personal experience and wisdom. Therefore, be familiar with each tool's usage and use, can draw the graph in the mind freely. Related article: Axure RP Interactive

Those prototype images that are refined and easy to use are always very attractive to me. However, so far I have not drawn a decent prototype. After I tried Visio and axure, I felt unsatisfied with ease of use. Prototype DesignAs the basis for communication between members of the product team, the diagram should clearly express the intent of the designer. For this purpose, the prototype map produced by a pen and a piece of paper is more original. However, due to the inconvenience of retaining an
, It should be better designed in advance, and you do not need to do too much, but there must be. Better than none. Projects generally involve a larger flow of people, because the long-term return is low. In addition, because of the low individual output, the staff's salary and level will be lower. Therefore, we should have a backbone staff to help you confirm the needs and design of the entire project, rather than making everyone feel
