ABOUT INTRODUCTION TO LOW-POWER MEMS MICROPHONES

  PSR is often specified by using a 217 Hz sq. wave to simulate the TDMA sounds created by GSM mobile radios and/or a swept sine wave across the audio band.MEMS microphone have hollow offers that include a substrate with pads which can be soldered to some circuit board or flex circuit, and a lid that makes a cavity the place the acoustic sensor as
