Comparing Analog and Digital Techniques for Measuring Noise Power Ratio

Techniques used to characterize device or subsystem performance through noise power ratio measurements
Comparing Analog and Digital Techniques for Measuring Noise Power Ratio Generally, noise power ratio (NPR) measurement is accomplished with a diode-based noise generator as a stimulus and a spectrum analyzer for analysis. However, a digitally generated stimulus and vector signal analyzer deliver more repeatable results in less time. Roland...
