Description
Tutorial aims to introduce fundamental DSP concepts and GNU Radio to new users. It consists of the following lab modules that are all based on Jupyter Notebooks.
- Lab DSP: GNU Radio will be introduced. It will be leveraged to generate mono/stereo sound, make filtering on generated sound. Sound card will be utilized to learn fundamental DSP concepts like sampling rate, aliasing, filtering (FIR, cutoff frequency, transient range, taps), decimation.
- Lab SDR: SDR hardware used throughout the labs is introduced: RTL-SDR. General purpose SDR application (SDR# or gqrx) is explored to receive samples from RTL-SDR. Spectrum monitoring (live and waterfall), demodulation is illustrated with it.
- Lab WBFM: WBFM signal may contain more than one signal: mono, stereo, sub-channels, HD, and a data channel. Flow-graphs are created to demodulate WBFM signals in GNU Radio. Mono/stereo sound, single/multi channel, real-time demodulation examples will be presented. User will also apply Python coding to demodulate WBFM signals.
