Recently, I applied an Onsemi LED driver circuit and needed to test the chip performance. The specification book stated that the chip can boost the voltage within 2.7V~5.5V, but my own test showed tha...
GSM is a communication technology that combines FDMA (frequency division) and TDMA (time division). All users in the network use different frequencies for communication. In the GSM900 frequency band, ...
I just started to learn DSP recently. I helped my teacher to adjust the program and use the SPI pin of TMS320F2812 to read and write SPI-E2PROM AT25320. Since I couldn't find relevant information on t...
Why should the ground wire of a digital circuit be connected in a closed loop? Doesn't this form a closed loop? Will the ground wire forming a closed loop not be interfered by external electromagnetic...
I am a novice, and I would like to ask if there is any expert who knows more about homemade impedance measuring instruments. Most of the ones I have seen are based on AD5933 as the core chip, but its ...
