STM32 Timer-Triggered ADC Sampling with DMA for FFT Analysis
Signal Analysis Parameters To analyze a signal using FFT, several key parameters must be defined: Target signal frequency: f Target signal period: T = 1/f Sampling frequency: fs Sampling period: Ts = 1/fs Total sample points: NPT Total sampling time: t = NPT × Ts Frequency resolution: f0 = fs/NPT Ca...
