ABSTRACT:
A supplied analog signal is modulated by comparing the supplied analog signal with a noise signal. As a result of each comparison, an output signal is generated having a first value if the supplied analog signal is greater than the noise signal and generating an output signal having a second value if the supplied analog signal is lower than the noise signal. Such modulation is useful in applications such as analog-to-digital conversion. The transfer function of the modulator is a function of the distribution of the noise source.
