What is a hysteresis modulator anyway?
A hysteresis modulator is an analog relative of SD modulation. Digital SD modulation is used in 1-bit DA converters and SACD audio. The analog equivalent has no clock and therefore doesn’t quantize the signal; the modulator switches whenever necessary, without having to wait for the next clock pulse. MUETA® therefore gives high performance while switching at a rather low frequency, without the need for noise shaping.
