When a signal generator outputs a modulated signal, the components inside the signal generator and an external test network comprised of mixers, filters, and cables, contribute frequency responses tha
Strong demand for faster data rate applications has triggered the need for new technologies capable of wide signal bandwidth. Cellular communication is transitioning from 4G to 5G to enable extreme da
Interference is an inherent side effect of new technology deployments using wireless communications. In a society that is moving (quickly) toward all-wireless technology, it is pertinent to detect, tr
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
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
In an earlier post, “How to Characterize RF Distortion – Part 1: CCDF Measurements,” I discussed how to evaluate waveform designs and statistical analysis of the signal power levels with complementary
If you’re an RF engineer, you’ll know that demodulation is the process of extracting the original information-bearing signal that was imposed on a carrier wave. But, why would you want to impose a sig
