Multiple domains provide designers and test engineers with complementary views of acquired signals. Oscilloscopes originated as instruments that measure electrical signals in the time domain. The ...

Time-frequency signal analysis techniques furnish a unified framework for examining non-stationary and multicomponent signals by representing their energy distribution jointly in time and frequency.

The launch of new products and options during June has boosted engineers’ choices for both time- and frequency-domain analyses. In the latter category, Anritsu added differential noise-figure ...

Monitoring and preventing coal-rock dynamic disasters are vital for safe mining. To investigate the time–frequency features of induced charge signals with coal damage and failure of roadways, the ...
