The Four Ws of Noise Figure

Nick Ben 2019.10.23

Modern receiving systems must often process very weak signals, but the noise added by system components tends to obscure those very weak signals. Sensitivity, bit error ratio (BER), and most important

How to Characterize RF Distortion – Part 3: Demodulation and Troubleshooting

Eric Hsu 2019.10.16

In previous posts, I discussed how to examine the distortion impacts through statistical analysis of the signal power levels with the CCDF curves and power analysis in the frequency domain. In this po

How to Characterize RF Distortion – Part 1: CCDF Measurements

Eric Hsu 2019.09.22

In today’s wireless systems, frequency spectrum is a finite resource. Complex digital modulation schemes improve spectral efficiency, but they also cause distortions. Characterizing RF devices involve
