AN-000111-PDM
https://invensense.tdk.com
A Pulse Density Modulation (PDM) microphone uses a Sigma-Delta modulator to oversample an acoustic signal at a high sampling rate. This digital PDM signal ...
PDM — Pulse density modulation interface
https://infocenter.nordicsemi.
The pulse density modulation (PDM) module enables input of pulse density modulated signals from external audio frontends, for example, digital microphones.
Design of a Multi
https://tomverbeure.github.io
It's time to bring all the pieces together and create a full signal processing pipeline to convert the output of a PDM microphone into standard PCM samples.
54.6.2.2 Decimation Filter
https://onlinedocs.microchip.c
The sigma-delta architecture of the PDM microphone implies a filtering and a decimation of the bitstream at the output of the microphone bitstream.
AN
