According to the evaluation plan, we will conduct performance testing in this article. There are many types of CPU benchmark performance tests, the most common one is coremark, and we will use...
I have been paying attention to the 2.4GHz and 5GHz dual-band WiFi of ESP32-C5. Now that ESP32-C6 has a development board, why is ESP32-C5 not yet in mass production?
Does anyone have any gossip?...
When I was simulating the saturation distortion of the RC coupled common emitter amplifier circuit, I found a strange waveform as shown in the figure below:In the above figure, when R1 is adjusted to ...
There are two ICs, one above the other. When the upper IC detects an error, the MOS tube is turned on. Then the output pins of both ICs are pulled low and the low level is output to the MCU. Then the ...
Like most technologies, oscilloscopes have also evolved with the times. Features that were once only available on expensive "top-of-the-line" oscilloscopes are now available on lower-priced oscillo...[Details]
Can a two-phase motor be converted to a three-phase motor?
Theoretically, a two-phase motor can be converted into a three-phase motor, but it requires a lot of modification and adjustment, inc...[Details]
