Recently, in digital image processing, I did not have an intuitive concept in the time domain and frequency domain. I will search for it and summarize it as follows:1. The simplest explanation The frequency domain is the frequency domain, We usually use the time domain, which is related to time, This is only related to the

It takes some time to find a new one. /// // Update ///// ///////////////////////

only the color, but also the computer's handling of the text. The computer will first convert the text to the corresponding number to do processing, such as the number is called "character encoding." In short, the computer will show everything in numbers.People who are familiar with computers often say something confusing, such as "open a file here, get a file handle," "Decrypt a file encrypted with the public key with the private key." So what do they call a "file handle"??—— is a number. What

The memory clock speed is the same as the CPU clock speed. It is used to indicate the memory speed. It represents the maximum operating frequency that the memory can achieve. The memory clock speed is measured in MHz (MHz. The higher the memory frequency, the faster the memory can reach. The memory clock speed determines the maximum operating frequency of the mem

The frequency doubling of the CPU. There is a ratio between the core operating frequency of the CPU and the external frequency, which is the multiplier coefficient. In theory, the frequency doubling is from 1.5 to infinite, but note that the frequency doubling is an interval

Speech Signal Processing (iv) Mel frequency cepstrum coefficient (MFCC) Zouxy09@qq.com Http://blog.csdn.net/zouxy09 This semester I have a speech signal processing course, and I am about to take the test. So I need to know more about the relevant knowledge. Haha, I have no lectures at ordinary times, but now I have to stick to it. By the way, I would like to make my knowledge architecture clearer and share it with you. The fourth knowledge point is M

High Frequency Circuit Wiring techniques in PCB Layout 1. Multi-board wiring High-frequency circuits often have a high degree of integration and a high wiring density. Using a multi-layer board is not only required for wiring, but also an effective means to reduce interference. In the PCB Layout stage, a proper selection of printing board sizes of a certain number of layers can make full use of the middle

To the users of Photoshop software to detailed analysis to share the principle and advantages of high frequency grinding. Analytical sharing: High-Low frequency principle: Photoshop high-low frequency grinding principle is to divide the image information into two parts, the color and light recorded in the low-

Author: Texas Instruments Richard Nowakowski and Brian King The benefit of increasing the switching frequency is obvious, but there are some shortcomings, designers should understand the pros and cons, in order to choose the most suitable switching frequency to be applied. This practical article will explain these considerations one by one. DC power converters with high switching frequencies are becoming po

I, "Detector, if I ask a statistician from the Bayesian school, if ......""[Throw] I am a neutron detector, not a maze guard. To be honest, is your mind broken .""[Throw]... yes" The stalk of the maze guard:There are two roads in the maze, respectively leading to the destination and traps. Each intersection has a guard, one of which only tells the truth and the other only tells lies, they all know what is behind the road and what each other is talking about. At this time, you can only choose on

With the rapid development of modern Wireless communication technology, Wireless Local Area network (WLAN) is widely used. WLAN uses wireless communication technology to transmit data, voice and video signals in the air, so that users can exchange information anytime, anywhere. Worldwide Interoperability for MicrowaveAccess (WiMAX) is a new broadband wireless access technology that provides high-speed internet-oriented connections, and the data transmission distance is up to 50 km. Currently, WL

(1) To customize the frequency domain Gaussian low-pass filter processing function of an image, it is required that the input parameters of the function include the image IMA before processing and the distance D0 (cutoff frequency) from the center of the frequency rectangle, and the output parameter is the image im2 after filtering processing. Custom Gaussian lo

The main mechanism for the time being: CPU level, device drive level, system platform level. The management grain degree unceasingly increases, forms the three carriages to drive the situation. CPU Level : The main implementation is relatively

Latest Advances in TD-LTE Testing At present, the first phase of core network, transmission, bearing and security testing work has been completed in the six test fields of TD-LTE. The results meet the test expectations, and all of them have entered the formal test conditions, in the future, the wireless performance, multi-antenna, terminal, indoor distribution system, network management and other aspects of the TD-LTE system will be carried out gradually testing. Aside from the past industrial t

In the DIY machine, memory is one of the necessary hardware, but in the selection of memory, in addition to looking at the capacity also need to see the frequency. But not all motherboards support high-frequency memory, how to see the motherboard support memory frequency It? This is a lot of DIY machine friends will come to a problem, the following triple small t
