PDM Decoder -DD404
A PDM decoder is a circuit that decodes a signal in the format of PDM (orthogonal component analysis) into multiple ADM (raw digital components). A PDM signal is a signal composed of many independent components, each of which has a fixed sampling rate. In the PDM decoder, each component of the PDM signal is converted into an ADM signal and can be further processed or output.
