50Hz, the output voltage of the inverter is 380 V and the current is 30a. at this time, if the output frequency is increased to 60Hz, the maximum output voltage and current of the inverter can only be 380 V/30a. obviously, the output power remains unchanged. so we call it constant power speed regulation. What is the torque?Because p = wt (W: angular velocity, T: Torque). Because p remains unchanged and W increases, the torque decreases accordingly.We

output drops to 4.45 V, leading to the failure of this test. 3. hdmi tx ddc/CEC Line Test It is critical to correctly connect the consumer electronic control (CEC) line (13th pin of the HDMI connector ). If the system is designed to not support the CEC function, the design engineer can leave the cables blank. Sometimes people want to connect the CEC line to the common purpose I/O of the video signal processing (VSP) chip, so as to allow subsequent extensions that may be needed. At that time, th

The following discussion is based on this usage scenario.System Delay Overview Analyze touch ecosystems with time series detailsIn the Android system, it usually represents the entire system delay. The value is measured in the Android version of the Jelly Bean. In the next article in the Touch series we will explain ho

As a global cooperative project, the birth process of the 709 proposal is the crystallization of wisdom and the product of compromise.2.1.7ITU-R recommendation BT.2020In the second half of 2012, the International Telecommunication Union radiocommunication Sector (ITU-R) issued a new generatio

the bottom of the screen. Once the electron beam reaches the lowest end, the electron beam closes and starts from the upper left corner. The pause between refreshes is called the Vertical Blanking Interval ). The display refresh itself at an incredible speed every second, so even if the screen is really black at a certain time, It is waiting for the electron gun to be re-drawn, your eyes-for the moment, you can still see the previous images. The usage frequency (Hz) of the refresh rate is the n

quantified bit rate. to reduce the bit rate, the closer the FS is to 2B, the better. in ITU-R601 recommendations, M = 6, the Brightness Signal Sampling Rate FS is 13.5mhz. for brightness signals of 625 rows/50 fields scan format, the number of sampling points in each row is 13.5*10exp6/15625 = 864. For brightness signals in the format of 525 rows/60 fields, the number of sampling points in each line is 13.5*10exp6/15734.265 = 858. As for the origin of the value 15734.265 mentioned above, I fou
