Theoretical Calculation and Analysis of Processing Circuit for Phase Difference Detection

Theoretical Calculation and Analysis of Processing Circuit for Phase Difference Detection

Background The core algorithm of the product I have been researching these days is the phase difference detection of the sine signals transmitted and received. On the STM32F407 processor, high-speed sampling of the received and transmitted signals is performed through DMA+SPI communication. An algorithm is designed to calculate the phase difference between the received and … Read more
