The multimedia is suspended. Let's talk about a few irrelevant theme words. Although it can behave like nothing, it is quite lost. I have never believed that scores can be used to measure a person's level or something, but I still have a bottom line on my requirements. The bottom line is that I stick to my own style of capital. Over the bottom line, all justified reasons will turn into the arrogant requirements of the 80 s. Why have I fallen to the point where I am not involved? How can I spend
voltage changes are discrete rather than continuous. In addition, the components of the loop are all implemented using digital circuits. Therefore, this phase-locked loop is called the full digital phase-locked loop (PLL ). The Digital Phase-Locked Loop consists of the Digital Phase Detector, reversible counter, frequency switching circuit, and n-frequency divider. The reversible counter and the N-divider clock are provided by the external crystal oscillator. VCO is not used to greatly reduce t

We know that the loss and dispersion of optical fiber are the two main factors restricting the transmission distance and capacity of linear optical fiber communication systems, especially in high speed optical fiber communication systems above gbit/s, the dispersion will play a major role, that is, because the pulse broadening will reduce the system capacity and the distance of transmissio

Basic Principles of Distributed Optical Fiber Temperature Measurement
1. Distributed Optical Fiber Temperature Measuring System Based on backward scattering principles can be divided into three types: Based on Fourier scattering, based on Raman scattering, and based on Bayesian scattering. At present, the development is relatively mature, and some products are applied to engineering Distributed Optical Fiber Temperature Measurement System Based on Raman scattering. Its sensing princi
mode is selected, and the color data of the corresponding color palette is 8 bits (up to 256 levels of gray scale ).
N LCD start control bit (ENB)
When ENB is set to 0, all LCD pins are used as general IO ports; When ENB is set to 1, the LCD controller is enabled.
(2) 1 control register (LCCR1)
The values of the four fields in this register are used to control the sequence of display related clock signals in LCD rows. They are the default counter values respectively.

TVS main parameters of diodes--reprintThe best way to deal with the damage to the device by instantaneous pulses is to draw the instantaneous current from the sensitive device. The TVs diode is connected in parallel with the protected line on the circuit board, and when the instantaneous voltage exceeds the normal operating voltage of the circuit, the TVs diode has an avalanche that provides an ultra-low resistance path to the instantaneous current, which results in instantaneous current being i

In addition, the HDMI interface provides a DDC display data channel, which sends configuration information and data format information to the video receiving device. The receiving device can read these E-edid enhanced extensions to display the information that identifies the data. Finally, the HDMI interface also provides the

Principle and method of laser rangingThe laser ranging coarse divided into two kinds, the first principle is roughly half the product of the speed of light and round-trip time, is the distance between the rangefinder and the measured object, taking the laser rangefinder as an example; the second is a method based on the principle of laser displacement sensor.There are roughly three methods of laser measurement, pulse method (laser Echo method), phase
, each clock cycle will have a hop, which is a bit synchronization signal.
Differential Manchester encoding is an improvement in Manchester encoding. It has a hop in the middle of each clock bit. The transmitted value is "1" or "0", which is determined by whether there is a hop change at the beginning of each clock bit.
Differential Manchester Coding has fewer changes than Manchester Coding, so it is more suitable for transmitting high-speed information and is widely used in Broadband high-speed
The last time we used AutoResetEvent to implement a production/consumer queue. This time we will use the Wait and Pulse methods to implement a more powerful version, which allows multiple consumers, each running in their own thread.
We use arrays to track threads.

Through the tracking thread, we can end our queue tasks after all threads are finished.
Every consumer thread executes a method called Consume. In a for loop, we can cre
