Due to efficiency, quality, and cost, digital communications systems play a major role in telecommunications, especially wireless services. With most digital modulation schemes represented as in-phase ...

We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals. We can pull all that together into an educational model for ...

Vector modulation is increasingly used in microwave and satellite communication applications, but generating vector-modulated signals for measurement can be difficult and expensive. However, using ...

Santa Rosa, CA. Keysight Technologies announced new enhancements for its FieldFox handheld RF and microwave analyzers. FieldFox analyzers now connect to Keysight’s 89600 VSA software for signal ...

Digital or vector modulation can provide increased spectral efficiency, higher data security, and higher quality communications. This comes at a cost of increased system complexity and a resultant ...

For those of us whose interests lie in radio, encountering our first software defined radio must have universally seemed like a miracle. Here is a surprisingly simple device, essentially a clever ...
