This is a Mechanical engineering problem about measurements.

2. A microphone in a measurement system is detecting an acoustic signal ( spherical pressure waves in airtraveling outward from a vibrating source ) . The microphone is sensitive to frequencies from 50 1 1 2 to 20. 000Hz and produces a 0.005 my to 0. 75 V' output proportional to the dynamic signal pressure detected . Thesensitivity coefficient of the microphone is 0.038 V / Pa and 20 Pa acoustic wave amplitude produces 0. 75V . A frequency spectrum will be created from data collected .a ) Sketch a data flow diagram from the microphone to the output recorded in a computer .b ) Specify measurement sample rate of to detect all frequencies captured by the microphone .C ) Specify the number of samples N to capture 5 seconds of the signal .$) Specify filters to reduce noise by 29. 3% or more below 60 Hz and above 20 , 000 Hz
