Evm is typically measured in decibels (db), and sometimes in percent. The matrix e[r t (n) r(n)] which must be inverted to calculate w opt or j min has dimensions mki × mki, which can be of very high order if a large number of secondary actuators are being driven by a large number of reference signals via control filters with many coefficients.if, for example, there are 6 reference signals, 4 secondary sources and 128 coefficients in each filter, the. The evm measurement block computes the vector difference between an ideal reference signal and an impaired signal.
