RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

There was a time — not long ago — when radio and even wired communications depended solely upon Morse code with OOK (on off keying). Modulating RF signals led to practical commercial radio stations ...

Newman-Kees Principal Consulting Engineer Frank Hertel says a friend recently brought him an old LPB 30-Watt AM transmitter for repair. It’s a good low-power transmitter, but this one had been abused.

[Stephen] recently wrote in to share his experiments with using the LimeSDR mini to conduct a bit of piracy on the airwaves, and though we can’t immediately think of a legitimate application for ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

Applications of radio-frequency identification (RFID) are widespread in today's well-connected society. Found in nearly every market including government, transportation, food, health care, retail, ...

Belar Electronics has unveiled its latest innovations for analog and digital AM modulation, as the RF monitoring firm has completed its updates for its legacy AMMA-2. The company says this allows for ...

New modulation schemes don’t come along very often. In fact, it has been years…decades really…. since any new modulation method has been invented. Remember there are only three basic ways a carrier ...

How to quantify the power-supply noise sensitivity of signal-processing chain loads. How to calculate the maximum acceptable power-supply noise. Strategies to meet power-domain sensitivity with ...
