Pulse Density Modulation (PDM) stands as a prominent digital signal modulation technique widely employed in the digitization and transmission of audio signals. This modulation method serves as an effective means of representing analog signals through a bitstream, particularly in applications related to microphone audio transmission. Operating within a voltage range of 1.8 to 3.3 volts, PDM has become a pivotal technology in the realm of audio processing, providing a robust solution for capturing and transmitting high-quality audio data in various electronic devices.
Application: PDM is a form of modulation used to represent an analog signal with a bitstream. Usually for microphone audio transmission.

PDM Electrical Validation
Use an oscilloscope for PDM electrical validation to ensure compliance with defined specifications. After an extended burn-in test, the oscilloscope confirms that the electrical characteristics of the signal meet the required standards.
