A Homomorphic Method for Measuring Secondary Amplitude Modulation A homomorphic processing, software implemented method for measuring secondary amplitude modulation (AM) is described. The accuracy of measurement of this method was tested on a series of synthetically produced AM and vowel signals. The homomorphic method provided highly accurate measurement of modulation frequency and modulation index. ... Research Note

A homomorphic processing, software implemented method for measuring secondary amplitude modulation (AM) is described. The accuracy of measurement of this method was tested on a series of synthetically produced AM and vowel signals. The homomorphic method provided highly accurate measurement of modulation frequency and modulation index.
