Difference between CCD sensor and CMOS sensor

Noise: Since each photodiode in CMOS needs to be equipped with an amplifier, if it is measured in megapixels, then more than one million amplifiers are needed, and the amplifier is an analog circuit, it is difficult to keep the results obtained by each amplifier consistent Therefore, compared

Zener diode with LM317

The LM317 regulator (Figure 1) is well known for its versatility in a variety of different functions and applications.

The standard and classic of the LM317 is that it is a three-terminal positive voltage regulator. Another simple and important configuration is

Fashion store lighting design points

Fashion lighting should mainly consider illuminance and color rendering. In terms of illumination, the illumination of the basic lighting of high-end fashion stores is 200~300lx, and the illumination should be appropriately reduced. The main use of key lighting highlights the products in or
