  • Digital signal converter
    Patent number: 7961020
    Abstract: A digital signal converter (CNV) converts a digital input signal (PCM) into a pulse width modulated signal (PWM), which is a binary signal that comprises pulses of varying width. The digital signal converter can operate in a signal mode and a transition mode. In the transition mode, the digital converter provides the pulse width modulated signal (PWM) by applying an anti-transient noise shaping function (NSH2) to a direct current modification signal (SC). In the signal mode, the digital signal converter provides the pulse width modulated signal by applying a signal noise shaping function (NSH1) to the digital input signal.
