The previous period of time to see a lot of concepts and knowledge, and found that because it is a quick pass through, so look at the confused, and then many places confuse the concept, especially about the image frequency domain part of the understanding (including image frequency domain filtering and so on), so the following summarizes this period of time to re-see "Digital Image Processing" (Electronic i

Frequency Domain Design of Multi-Band FIR Digital Filter Time: 15:34:47 Source: modern electronic technology Author: Zheng jiachun 0 With With the advent of the information age and the digital world, digital signal processing has become an extremely important discipline and technology field. Digital Signal Processing in communication, voice, image, automatic control, radar, military, aerospace, Medical and household appliances have been widely used in

MP3 is only a type of audio format. However, audio has several important parameters, such as kHz, bit, audio channel, and kbps. the formats are different, and the algorithms are different. Therefore, when the above parameters are the same, the quality of different formats varies greatly. VBR is a kind of dynamic sampling. For more information, see the following description. After reading this, you can say something. Audio sample Interpretation Digital audio systems reproduce the original sound

Recently learning music automatic labeling process, saw the use of MFCC extract audio features of the content, specifically found on the Internet Information, learning about the relevant content. Most of this note was taken from the blog post http://blog.csdn.net/zouxy09/article/details/9156785, which I added when I marked and corrected it for future reference. speech Signal Processing (four) Mel frequency cepstrum coefficient (MFCC)[Email prote

In many factors that affect blog viscosity, the frequency of blog updates may be the most overlooked but the impact of one of the most important, it is true, fundamentally, users like a blog or not, based on the quality of their content, and the blog update frequency does not have much relationship, but, The content itself does not effectively translate the new users who are attracted to the site's loyal us

See some friends want to adjust the CPU frequency and monitor it, took a little time to check the new stand, the result found such a good thing.Update//////////////////////////////////Actually, there's one simple way.Code:sudo dpkg-reconfigure gnome-applets then select OK and yes, add the CPU frequency monitor to the panel, and install the cpufreq-selector automatically. You do not have to install cpufrequt

By dynamically changing the CPU voltage, you can adjust the CPU frequency. The CPU clock frequency can be changed dynamically by changing the clock multiple. Some processors with adjustable CPU main frequency clock multiples can switch dynamically between different main frequencies and operating voltages without the need for kernel or user intervention. Terminol

What is a frequency converter. The frequency converter is the power control device which transforms the power frequency supply into another frequency by using the switching function of the electric semiconductor device. The frequency converter is the power control device w

Intel Core-frequency Acceleration technology is a unique feature of Intel's high-end processors and a new Intel technology. This technique can be understood as automatic overclocking. When the core-frequency acceleration, the CPU will automatically adjust the CPU frequency according to the current task amount, thus heavy task to play the greatest performance, lig

The Joule is filled with the heat generated by the electrolyte in the capillary in a high electric field. High-frequency heating machine full name "High-frequency Induction heating Machine", also known as high-frequency induction heating equipment, high-frequency induction heating device, high-

1. clock speed The clock speed is also called the clock frequency. The unit is MHz (or GHz), which is used to indicate the speed at which CPU operations and data processing are performed. CPU clock speed = frequency X frequency doubling coefficient. Many people think that the clock speed determines the CPU running speed. This is not only one-sided, but also a mi

The Ddfs-direct digital Frequency synthesizer Direct numerical frequency synthesis technique can be used to generate periodic signals of arbitrary waveforms. The so-called Ddfs is simply a look-up method that internally maintains a lookup table that stores a periodic waveform. So the lookup table actually gives a mapping of the phase-to-function value:Here the phase ω is the linear function of the time t.Ad

We are the most commonly used in fashion blockbuster some of the processing skills, to tell you how to lose the real premise of improving skin texture, remove the screen flaws. Triple recommended: photoshop7.0 Mini version free download | Photoshop CS5 Chinese free Download | Photoshop free Download Portrait processing is an art, when dealing with the characters to look as perfect as possible, but also to ensure that the adjustment does not distort the operation. How to balance these two point

In a digital system, a clock pulse of multiple frequencies is often required as the driving source, which requires the frequency of the FPGA's system clock (too high) to be divided. The frequency divider is divided into odd frequency, even frequency, half-integer and fractional, in the FPGA system where the clock is no

Memory frequency refers to the frequency, in MHz (megahertz), that the display is working on the video card by default. Video memory frequency to a certain extent reflects the speed of the video memory. Video memory frequency with the type of video memory, the performance of different, SDRAM video memory generally work

Label: style blog HTTP use ar sp 2014 art C Although the phase frequency response should reflect the processing time of different frequency signals, it does not mean that the larger the phase frequency response, the longer the system processing time. We can know from a simple sine signal exp (J * w * n) that the phase is w * n, that is, the phase is not only rel

What is a frequency conversion power supply?The AC Variable-frequency power supply technology has been widely used in developed countries. Its principle is to convert the AC power in the mains supply through AC → DC → AC, and output it as a pure sine wave, the output frequency and voltage can be adjusted within a certain range.Why is the

First of all, we want to explain that the memory capacity is not within the scope of our discussion, after all, 4GB has become the mainstream of today, to deal with the general application and 3D game is not a problem, only in some specific applications, the need for greater capacity of memory. We're talking more about frequency today. At present, the ddr3-1600 is the absolute mainstream, but the higher frequency
