adaptive balancing technology is used, anti-interference capability is enhanced, inter-code interference is overcome, and long-distance non-relay transmission can be realized. The HDSL system is placed on the switch terminal and the user end. The system consists of a transceiver, A multiplexing and ing part, and an E1 interface circuit. The transceiver consists of two parts: sending and receiving. It is the core of the HDSL system. The sending part converts the input HDSL single-channel code st
. It uses a simple comparator to compare the level of the sound to be played by the speaker with the sound picked up by the current microphone. If the former is higher than a threshold value, it is allowed to be passed to the speaker, and the microphone is closed to prevent it from picking up the sound played by the Speaker and causing remote echo. If the sound level picked by the microphone is higher than a certain threshold value, the speaker is disabled to eliminate echo. Because echo suppres

The principle is to suppress howling through traps. For example, Sabine's fbx series feedback eliminator is a nine-section narrowband automatic pressure limiting device controlled by a microcomputer. It can better distinguish self-excitation signal from music signal, when the system is self-excited,
Quickly respond and set a very narrow digital filter on the feedback frequency. The trap depth is also automatically set, and the filter b

In vim, I introduced the concept of mode in vim and how to move the cursor in VIM in multiple ways. This section describes copying, cutting, pasting, undo/Redo, and search operations. Let's get started!
1. Copy, cut and paste
Copy, cut, and paste are the most common operations for text editing. Vim also has corresponding operations, but their naming methods have changed in VIM: Vim calls cut as delete, copy as Yank, and paste as paste. When you use Vi

In the GUI, we can copy and paste it freely. But in the character interface, we have to select with the mouse, then click the right key, select copy, and then go elsewhere to Ctrl-v. In addition, for those VIM that have not been configured, the VIM clipboard and the X Window clipboard are not shared yet. This is not smooth in the Process of code words. Next, we will try to solve this problem.
First, we need to share a clipboard with VIM and X Window, so

Only the value of $firstname is Kevin, and this condition returns true if the value of $lastname is yank. The meaning of and is that only two
