WebThe experimental results show that the chirp signal improves the signal-to-noise ratio and expands the applicable time-of-flight algorithm. The waveform pulse width after cross-correlation is 1.5 μs, compared with 40 μs before. The time-of-flight uncertainty can achieve 1.03 ns compared to 8.6 ns before. WebAug 21, 2015 · A chirp is a much more complex sound. To get a sine wave sweep, you probably want a sine function that doesn't use up most of the Arduino executable space. … WebFor a sine wave modulation, the modulation index is seen to be the ratio of the peak frequency deviation of the carrier wave to the frequency of the modulating sine wave. If , the modulation is called narrowband FM (NFM), and its bandwidth is approximately . Sometimes modulation index is considered as NFM, otherwise wideband FM (WFM or FM). triathlon bamberg 2023
