The audio spectrum of the voice data (1) is mixed with a fixed carrier frequency f c (2).This results in two spectra: one that is the sum of the original sectrum and the carrier (3), and one that is the difference of the two signals (4).A low-pass filter (LPF) is then applied to filter-off the sum and leave only the difference, effectively resulting in a mirrored audio band (5).
