WebThe number of iterations grows exponentially when decreasing crest factor. For a multisine sequence of length 32768 it needs only 4-5 iterations to halve the crest factor from 4 to 2, but to get the crest factor < 1.5 it needs several hundreds or more than thousand iterations. WebNov 20, 2024 · The ratio between two (linear) values, is equivalent to the difference between the two decibel values. Say you have 0dB peak level (linear value = 1) and -12dB RMS (linear value ~0.25). The peak to average ratio or crest factor can be both expressed as: crestfactor_dB = peak_dB - rms_dB = 0 - -12 = 12. or.
