First, let's get to know several "regions": "hot" refers to areas directly or indirectly connected to the AC power grid; "cold ground" refers to a region that is not connected with the power grid. A signal "Ground", also known as a reference "Ground", is a reference point with zero potential, it is the public end that forms the circuit signal circuit. The "ground" of protection is in Class I electrical equipment (it cannot rely solely on insulation for protection) in order to protect the securit

(C) and the four signals of the loop channel (S), which are encoded and then combined into the dual-channel signals of LT and RT, during replay, the decoder restores the encoded dual-channel Composite Signals LT and rt to the encoded left, right, middle, and surrounding independent signals that do not affect each other, after amplification, enter the left speaker, right speaker, center speaker, and surround speaker respectively. To ensure sound symmetry, the surround speaker uses the Left and R

of logic gate The next step is to use a transistor to make a logic gate circuit. NOT first. The Base of the transistor is used as the input, the collector is used as the output, and the emitter is grounded. When the input is 1 (high), the current flows to the emission pole, so the output is 0; when the input is 0 (low), the current flows out from the collector, so the output is 1. AND. This requires two transistors. Only when the input of the two base poles is 1 (high level) will the curre

product quality and output, and the heavy will lead to accidents and cause major economic losses.There are three basic elements for interference:(1) interference sources. It refers to the components, devices, or signals that produce interference. The mathematical language is described as follows: du/dt. Where di/dt is large, it is the interference source. Such as lightning, relay, thyristor, motor, and high-frequency Clock may all be sources of interference.(2) Propagation Path. A channel or me

features such as overclock and input decoder license, which can be mined by itself. In addition, if your TV supports 24-frame playback, you can also set it in the video to be 24 p globally. You can also set it to switch from 24 p only when you play back the video.Audio Output Raspberry Pi 2 does not have an optical fiber output interface, so if you want to export audio to an independent power amplifier, You need to configure a pass-through on the TV,

The speaker sound is okay, but the Speaker cannot be turned on at work. When the connector is set to "anolog headphones" in the audio output preferences, only the headset is output, and the sound heard by the headset is very small, adjusting the output volume to a large amount does not have any effect. After finding a circle on the internet, I finally solved the problem, as shown below: Enter alsamixer on the terminal and press enter to display the sound card setting option. Here, the front
