That is useful for signal analysis and mathematical treatment, but it isn't useful for hobbyists like myself that would just like to see what such signals look like.

SpletA Pulse Density Modulation (PDM) microphone uses a Sigma-Delta modulator to oversample an acoustic signal at a high sampling rate. This digital PDM signal is output … SpletThe I2Sn_CLK is derived from the system clock, so this poses a limited I2S bit clock divider options. This can have implications for other peripherals in the system that would take the clock from the system clock. Example: • Fs = 16 kHz • I2Sn_CLK = 1.024 MHz (64xFs) Derived system clock frequencies: • 2.048 MHz (/2) • 4.096 MHz (/4)
