AD/DA conversion

What does 'MS/s (MSPS)', used to express the conversion speed of an AD converter, mean?

  1. AMegasiemens per second
  2. BHow many million times per second it can sample (convert)
  3. CThe number of milliseconds per conversion
Show answer and explanation

Answer: B. How many million times per second it can sample (convert)

MS/s stands for mega samples per second and indicates how many million times per second the converter can sample and convert. For example, a 100 MS/s ADC converts 100 million times per second. By the sampling theorem, the highest signal frequency it can handle is half that.
