Noise shaping circuit, digital - time - transducer, in a manner similar to that of - digital - transducer, digital - analogous to that of - transducer, a frequency synthesizer, the transmitter, receiver, transceiver, a method for forming of noise in an input signal

摘要

A noise shaping circuit (120) according to one example, comprises a forward signal path (130), which is formed an output signal (os) based on an input signal (is) to be produced, a coupling signal path (140), which is adapted to provide a feedback signal (fs) based on the output signal (os) to the forward signal path (130) occurs, and a dither - generator (160), which is adapted to provide a dither - signal (ds), and to produce the dither - signal (ds) in the forward signal path (130), for coupling the input signal (is) to be modified, and in the feedback coupling signal path (140). The insertion of a shaping circuit (120) according to one example, a total noise behavior improve.
