THE 2-MINUTE RULE FOR INTRODUCTION TO LOW-POWER MEMS MICROPHONES

  PSR is generally specified by using a 217 Hz square wave to simulate the TDMA sound produced by GSM mobile radios and/or maybe a swept sine wave through the audio band.To guage the effectiveness with the MEMS microphones, some critical parameters really should be analyzed. Figure 1 highlights The important thing acoustic specifications of the mi
