When it comes to amplification, the principal parameters are gain and fidelity of the output relative to the input. Gain, denoted by β (Greek letter beta), is the ratio of output voltage, current or power to input. An amplifier by definition has a power gain greater than one. Measurements that characterize amplifier gain serve as […]

Measuring the behavior of electronic filters
Passive electronic filters are composed of one or more passive components including resistors, inductors and capacitors. In contrast, active electronic filters also contain an amplifier composed of transistors or op-amps. The point of electronic filters is to pass some frequencies while blocking others. Depending upon the configuration, they selectively attenuate high frequencies (low pass), low […]
Book Review: Create Your Own EMC Troubleshooting Kit
Create Your Own EMC Troubleshooting Kit (Volume 1): Essential Tools for EMC Troubleshooters by Kenneth Wyatt shows you the tools you need to start tackling interference problems. Tracking down and mitigating electrical interference isn’t black magic, though some would have you believe that. Armed with some knowledge on how signals travel and with the right […]
Basics of QAM reception and its measurement
A conventional AM broadcast generally begins in the studio as a music or voice audio signal. The audio signal modulates the amplitude of a radio-frequency electrical signal. This AM signal–also referred to as double-sideband amplitude modulation to distinguish it from single-sideband modulation–produces equal frequency sidebands on either side of the center frequency. In single-sideband modulation […]
Compliance tests cover 2.5/5/10GBASE-T1 automotive Ethernet speeds
Rohde & Schwarz, together with connector and cable assembly manufacturer Rosenberger, have successfully demonstrated compliance testing for MultiGBASE-T1 supporting 2.5/5/10GBASE-T1 automotive Ethernet speeds, based on the OPEN Alliance TC9 working group test specification. This development enables vehicle manufacturers and component suppliers to have confidence in the performance of future, high-speed in-vehicle networks. Automotive applications such […]
