This is a fork of a https://github.com/slazav/pico_osc.git project written by V.Zavjalov. As a part of the original project, this fork contains only tools for processing .sig format, all device-related programs were excluded, Further is an original Readme.md file with the above-mentioned modifications.

• sig_filter -- Program for processing signals recorded in .sig format.

I'm using a simple custom format SIG for recording signals. It contains a text header and binary data from oscilloscope. There is also SIGF variant written in frequency domain (it is possible to reduce frequency range and make files a lot smaller). Sig_filter program does a lot of operations with signals.

• sig_pngfig -- Working with PNG spectrograms with fig wrapper. It is possible to convert sig file to a png spectrogram with additional information about original time and frequency range; put it in a fig file (for xfig vector editor), manually mark some features and then use sig_filter to extract data from sig files using these marks.

• sig_viewer -- TCL viewer for signal (and text) files

• sig_python -- a simple python library for reading sig files

• signals -- signal examples

• modules -- I'm using my mapsoft2 build system with local set of modules. See https://github.com/slazav/mapsoft2-libs
