understanding digital signal processing

Http://www.cnblogs.com/taobataoma/archive/2007/08/30/875743.htmlsignal is a very important part of Linux programming, this article will detail the basic concept of signal mechanism, the approximate realization method of Linux to signal mechanism, how to use signal, and several system calls about signal.

the continuous improvement of the version, the function of MATLAB becomes more and more powerful, and the application scope is more and more extensive. Now it covers almost all scientific and engineering computing fields, such as simulation technology, automatic control, digital signal processing, digital image

See UNP today before the discovery of signal to understanding is really superficial, today took to study alone under discussion.Signal, this function is relatively simple, given a signal, the signal processing function can be, of course, the function is simple, its function

types: low-pass, high-pass, and band-resistance. The functions of various filters are shown in the following table:Simulated Filtering:The filtering method implemented by the analog circuit first uses a simulated filter before sampling, which can improve the signal quality and reduce the workload and difficulties of subsequent data processing, such as the Anti-mixing filter in the

is divided into CMOS and CCD) to convert the uptake target into an image signal and transmit it to a dedicated image processing system, digital signals are converted based on Pixel Distribution, brightness, color, and other information. Image systems perform various operations on these signals to extract target features, then, efficient machine control or variou

In the field of logical design, only a single clock domain is involved in the design of a few. Especially for some complex applications, FPGAs often need to communicate with signals from multiple clock domains. There may be a phase difference between the two clocks involved in an asynchronous clock domain, or there may be no frequency relationship, that is, a different frequency phase that is often said to be different.Figure 1 is an asynchronous communication instance across a clock domain, wit

Signal is a very important part in Linux programming. This article will introduce in detail the basic concepts of the signal mechanism, the general implementation of the signal mechanism in Linux, and how to use the signal, and several system calls related to signals. The signal
