About Sigmira
Sigmira is a software-defined radio application that displays wideband signals in real time. It provides spectrographic, waterfall, and phase-plane displays, giving users different visual ways to examine radio activity across a band. The application can also demodulate a range of radio signals, including military, utility, commercial, and amateur-radio transmissions. Demodulation extracts the information carried by a received signal so it can be monitored in a usable form. The visual displays complement this by showing how signals vary across frequency and time. Sigmira is intended for users working with software-defined radio equipment who want to view and decode signal activity. It combines real-time visualization with demodulation, making it useful for radio monitoring and experimentation. The particular frequencies and signal types depend on the connected receiver and configuration.
