Modulation Transfer Function Measurement with Maximum-Length Sequences
The complex modulation transfer function (CMTF) has important applications in many fields, including audio. For example, the magnitude of the CMTF or MTF is the basis for the speech transmission index (STI). A well-inown theorem shows how the CMTF of a noiseless linear time-invariant system can be derived from its impulse response. When maximum-length-sequence (MLS) methods are used, this theorem can be extended to include noise-contaminated as well as weakly nonlinear systems. Furthermore, with MLS methods there is no requirement that the interfering noise be stationary.
