Subject: How one can demonstrate that microphone is a nonlinear device? From: Hafiz Malik <hafiz.malik@xxxxxxxx> Date: Mon, 11 Jun 2012 14:13:33 -0400 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--001636c5a944d3ad7604c2364eb9 Content-Type: text/plain; charset=ISO-8859-1 Hi Every 1, Microphone is generally modeled using a second-order nonlinear function, that is, y(n) = ax(n) + b x(n)^{2} where x(n) is the microphone input. How can one demonstrate this non-linearity? Any suggestions/comments/literature in this regard.
