System Identification with MLS

• Length of MLS:

• • at least the length of the expected IR

• SNR:

• • crest factor: 1 best SNR we can get!
  • higher than PIE
  • • fs=48kHz, T=0.7s: SNR gain: +45dB
    • the same SNR with PIE leads in the
    • measurement duration of 9 hours

• Averaging of time variant systems

• Very sensitive to nonlinear distortions
