The course introduces the soft green effect color rendering method. The tutorial omits some of the actual parameters of the control, with only a few hints. When mixing, you need to try different values. Original Artwork 1 Effect 1

failure One, may be computer and modem connection is bad; Solution: First check whether the modem and hair normal connection, if the connection out of the problem, restart the cat, in turn to see whether the computer failure to solve. 　　Failure

Tip: You can modify some of the code before running scroll bar modulation and change background effects Hint: This is a color adjuster, now This example simply changes the color of the background, you can apply this method

The color palette of the characters does not necessarily require tedious process, the key is to be able to control a good hue, to apply freely. This way, even with simple steps, you can pull out a very amazing effect. The color palette of the

Photoshop Tutorial: Make beautiful photos of elegant style. First look at the effect and original image: The following is a detailed tutorial: The first step: use Photoshop to open the original image, copy a layer for layer 1, in order

We have already designed some knowledge about vrotelnet telnet. So for this part of content, we will detail it again today. In the network management process, you often need to modify the vro configurations, such as modifying the wide area network

Final effect First, open the original image, create a curve adjustment layer, the parameters set as shown below. Second, create a gradient map adjustment layer, color settings as shown below. Third, create a

1, we on the phone to open the Dragonfly FM home page, and then click as shown in the Picture button, open the Radio category 2, then there are many channels, we click to select "Radio" effect as shown below. 3, then our Radio page can

This tutorial is more about text descriptions and layer references, and there are no process effects diagrams. The author provides only the ideas, details and some parameters of the settings also need their own heart to grasp. This tutorial is more

Micro-letter Speaker mode In fact very simple only a few steps can be achieved, below the Android phone for example. 1. We click on the phone in the micro-letter, enter and then click on the lower right corner of "I" (as shown in the following

In the debugging of the ICU communication equipment, because the serial communication of the old fault, so I suspect CF implementation of the SerialPort class whether there is a problem, so finally decided to use a pure API function to achieve

This tutorial mainly use Photoshop to pull out a day of bright white effect, recently this effect is very popular, the ultimate effect of warm and elegant, like this effect of friends together to learn it. This tutorial mainly use Photoshop to pull

Photoshop Red tone color Sunset pictures tutorial, graphic tutorials. Original: Effect Chart: Original: Effect Chart: 1. Open the picture, ctrl+alt+~ Select the High light section Create a curve adjustment layer The settings are as

Deal with the messy parts of the first fuzzy processing, especially the background part. Then appropriate to the character of the skin and then the whole polishing, so that the character part of a lot of prominent. Color before the first analysis of

Today we introduce a character Photo palette tutorial to bring up the red color effect of girls ' photos. Today we introduce a character Photo palette tutorial to bring up the red color effect of girls ' photos.The final effect chart is as

channel, it is unclear) 2Mbps Transmission Using the DQPSK (differential quadrature phase shift keying), a total of 4 phase carrier, each carrier difference 45 °, so that the information carried in the RF signal than DBPSK added a cup, each carrier represents two bit of data.The same transmission 01001101, DQPSK only half the time (the retention period of each carrier is constant) 5.

Communication Algorithm 4: Nine debugging methods: theoretical error rate and actual error rate, and nine Error Rate 1. there are nine modulation methods, including BPSK, DBPSK, 2ASK, 2PSK, PSK, opsk, DQPSK, 16QAM, 64QAM, and theoretical error rate formula. You can view the book and use matlab to draw a picture to understand the theoretical error rate. 2. SNR :. Channel environment: AWGN Simulation proces

. Because the modulation technology used in MMDS is mainly the phase shift keying PSK (including BPSK, DQPSK, QPSK, etc.) and the orthogonal amplitude modulation QAM modulation technology, it is impossible to achieve the non line-of-sight transmission, which is difficult to be popularized in the present complicated urb
