Course Introduction：PHP7 is a brand new version of the PHP programming language, which has been greatly improved mainly in terms of performance. Official documents show that PHP7 can achieve twice the performance of PHP5.x version. At the same time, the syntax of PHP is sorted out, and many popular syntax formats in other languages are provided. The commendable thing is that after making such a big change, the compatibility of PHP7 is still very good. For the vast majority of applications, you can migrate to the PHP7 version without making any modifications.

Course Introduction：The functions and functions of the lm393 chip are: 1. The output load resistor can be connected to any power supply voltage within the allowable power supply voltage range, and is not limited by the Vcc terminal voltage value. The sink current of the output part is controlled by the possible drive and β of the device. value; 2. When the limit current of 16mA is reached, the output transistor will exit and the output voltage will rise quickly; 3. The output saturation voltage is limited by the γSAT of the output transistor of about 60ohm. When the load current is small, the output transistor's low offset voltage (approximately 1.0mV) allows the output to be clamped at zero level.

Course Introduction：The functions are: 1. Convert the data signal sent by the source into an analog signal suitable for analog channel transmission; 2. At the receiving end, it synchronously extracts and phase-locks the synchronization information sent to generate the same frequency as the source. , a carrier in the same phase, used for timing and sampling of the signal sink to ensure synchronization of the signal source and the signal sink; 3. Compensate for the interference damage to the signal caused by harmful factors; 4. Utilize the orthogonality of the seat number and use a variety of coding and modulation methods to achieve Channel multiplexing; 5. Direct connection; 6. Automatic redialing; 7. Soft phone book, allowing users to control calls through software; 8. Baud conversion.
