ADCADC is the English abbreviation of analog-to-digital converter, which is an electronic component that can convert analog signals into digital signals. Usually, the signal is sampled and held, and t...
Specifically, a voltage signal is input from the outside, and then converted to a digital value through AD. I want to compare it with the preset value. If it is higher than the preset value, it will b...
Dynamic detection of TD-SCDMA network The product we developed uses TD module. When the network signal is good, it should be fine to use it normally. When the network signal is not good (no network), ...
Help~~~~~~I used to work with single-chip microcomputers, but now I need to use DSP to receive the signal from a light spot encoder. I can only find QEP circuits on the Internet, but it doesn't explai...
To measure wind in the research and development instrument, we only need to measure whether there is wind passing through the pipe. The working condition is to measure whether there is wind passing th...
