Piezoelectric crystals are the core of imaging. The probe uses the piezoelectric effect of the crystal to convert high-frequency electrical energy into ultrasonic waves for outward radiation, and rece...
I sampled 8 40KHZ square waves (25us per cycle). The sampling frequency is 500KHz, which means one point is sampled every 2us. I cannot restore it. There are only a few high pulses with a long interva...
Abstract: This paper introduces the bootstrap design and application of the IDMA interface of the ADSP-218X series DSP chip. In terms of hardware, it introduces the characteristics of the IDMA interfa...
Input voltage: constant 12V Duty cycle D of PWM wave driving IGBT varies from 0.01 to 0.9 Output voltage range: only 0.2 to 4.8V Theoretically it should be 0.12 to 10.8V. What is the reason? ? ? [colo...
