INTRODUCTION TO LOW-POWER MEMS MICROPHONES SECRETS

  PSR is usually specified with a 217 Hz square wave to simulate the TDMA noise generated by GSM cellular radios and/or possibly a swept sine wave over the audio band. 2.6 Dynamic selection: Dynamic array is the vary from the lowest to the very best sign that a microphone can tackle. For a MEMS microphone, it may be defined as the gap from self-
