European GNU Radio Days Introductory Tutorial 1 (JM Friedt)

Introductory tutorial on using GNU Radio Companion (3.8):

0:00:00 SDR architecture basics -- why SDR
0:02:35 quantization in time and level: dynamic range and aliasing/spectrum periodicity
0:07:30 real source: time domain and frequency domain
0:08:30 signal types, throttle block
0:16:10 variables, sliders (GUI Range), capital letters in variables
0:22:30 complex signals (I,Q demodulation)
0:33:46 decimation: zooming on the spectrum ; need for low-pass filtering
0:42:00 low pass filter cutoff frequency and transition width: demonstration with the Filter Design Tool
0:58:10 Filter characterization: frequency sweep v.s noise source approaches
1:03:40 AM transmitter
1:08:25 Audio sink (remove throttle)
1:10:40 gr-osmosdr block v.s RTL-SDR architecture
