标签: 数据转换器 信噪比 SNR 噪声频谱密度 NSD
his video is part of the TI Precision Labs – ADCs curriculum. The 1st part of the presentation will go over the concept of Signal to Noise Ratio or SNR, by defining the meaning of SNR. A more detailed examination of the different components that make up the noise portion of SNR will be explored. This includes thermal noise, quantization noise, and jitter of the quantization clock. An example of a calculation of SNR that is dominated by jitter will be provided. The 2nd part of the presentation will examine the concept of Noise Spectral Density or NSD, and describe how this is different from SNR. Finally a design example will be presented which will highlight how NSD can be used to estimate the performance of the output of a DAC as it pertains to noise floor related performance specifications.

This video is part of the TI Precision Labs – ADCs curriculum. In this video we’ll first look at what modulation is and some common types of modulation. Then we’ll dig into phase and amplitude modulation and the math behind it, in order to introduce the concepts of real modulation and complex modulation. Finally, we’ll discuss uses of complex modulation and finish with an example to connect the concepts.
