The quantization and sampling accuracy requirements for an analog to digital converter (ADC) in an MR scanner are analyzed. In particular, we develop an equation detailing the impact of sampling jitter when direct sampling high field MR signals. Calculations indicate that direct sampling should be practical, without impacting image quality, even up to 7T.
