SigDigger

Graphical Digital Signal Analyzer

SigDigger has your typical AM/FM/LSB/USB demodulation and audio playback features. However, it also has some key additional features that make it worth taking a look at if you're interested in reverse engineering, or taking a closer look at digital signals. The features include: * Both realtime and replay analysis modes * Analog audio playback (AM, FM, LSB and USB) * Baseband recording (full spectrum and per-channel) * Per-device gain presents * Dynamic spectrum browsing * ASK, FSK and PSK inspection * Gradient-descent SNR calculation * Different spectrum sources (cyclostarionary analysis, signal power…) * Symbol recording and visualization * Transition analysis
