通信过程中,对信号传递,数据通过经常是可以转为正态进行分析,注意很多分布都是非正态的,电子行业里,二项分布,泊松分布很多见.但都是可以转正态的,有些时候这些分布参数也可以转换为sigma .所以但从字面意义,Noise应该仅仅是一个影响通信的因素,如果你能准确正确测量noise的话,那么noise的分布可以使用Si...
NoiseSigmaForFeature(mapping=None, *, ignore_unknown_fields=False, **kwargs) Noise sigma for a single feature. Attributes Name Description name str The name of the input feature for which noise sigma is provided. The features are defined in [explanation metadata...
A sample-and-hold (SAH) phase detector (PD) is clocked in such a way (using a reverse clocking mode) so as to avoid quantization noise increases due to folding that is generally associated with conventional charge pump based phase detectors. The PD is clocked with a clean clock (reference...

总之,Sigma-Delta Modulator 是一种 PDM 脉冲密度调制,PDM 的调制频率是变化的,通常比 PWM 的调制频率要高。 Noise shaping(噪声整形) Noise shaping 中的 Noise, 指的是 A/D 过程中的量化噪声,它当然与调制方式有关。 如果我们从频谱角度看 1-bit 码流,因为 PWM 调制频率是固定的,量化噪声的能量会更集中在...
The operation circuit includes a plurality of operation stages that operate with timing according to all of the clock signals for high-order sigma-delta modulation. Thus, noise may be dispersed for minimizing noise coupling. The SDM is used to particular advantage within a fractional-N phase-...
A sigma-delta fractional-N frequency synthesizer (FS) achieves the phase noise performance using a spur supression method. A sigma-delta modulator is represented in this work which reduces spur in output frequency spectrum of the fractional-N frequency synthesizers. This technique also improves the ...
The AXIOM_PULLFIRDAC is a high accuracy sigmadelta digital-to-analog converter. The low out-of-bandnoise (OOBN) down to -60dBFS makes the converter ideally ...
