12:50, 11 May 2024 ATSC04-Ch38.jpg (file) 324 KB ATSC 1.0 spectrum and spectrogram. The spectral line on the left edge of the signal is the pilot tone. 1
12:31, 11 May 2024 ATSC-Ver3-Ch25-02.png (file) 989 KB Spectrum and spectrogram of ATSC 3.0 signal. The portion of the signal seen to the right of the 3.0 signal is a ATSC 1.0 transmission. The pilot tone for that transmission is the spectral line on the right. 1
19:32, 13 April 2024 NwrReceiver.jpg (file) 327 KB NOAA Weather Radio (NWR) receiver, to include both frequency and time domain displays. This flowgraph demonstrates the FFT Low Pass Filter block. 1
18:40, 13 April 2024 Complex2ArgDemo.jpg (file) 239 KB This flowgraph demodulates a FM broadcast station. It demonstrates using the "Complex to Arg" block. The blocks from the output of the lowpass filter to the output of the "Multiply Const" block are equivalent to the "Quadrature Demod" block. 1
17:22, 13 April 2024 MeasureFmSignalPower.grc (file) 17 KB Flowgraph used to measure the signal-to-noise ratio (SNR) of a FM broadcast station. This flowgraph demonstrates a use of the Complex to Mag^2 block. 1
17:20, 13 April 2024 ComplexMagSquaredSpectrum.grc (file) 21 KB Flowgraph used to create a basic spectral display. This is used to demonstrate how a spectral display is created using the FFT and Complex to Mag^2 blocks. 1
17:13, 13 April 2024 ComplexMagSquaredSpectrum.jpg (file) 412 KB Flowgraph used to create a basic spectral display. This demonstrates several blocks, including the FFT and Complex to Mag Squared blocks. 1
17:03, 13 April 2024 Complex-to-Mag2-block-properties.png (file) 14 KB Property window for the Complex to Mag Squared block. 1
17:00, 13 April 2024 Complex-to-Mag2-block.png (file) 5 KB This is the GRC display of a Complex to Mag Squared block. 1
16:55, 13 April 2024 Measure-signal-power-display.png (file) 52 KB Display from the flowgraph used to measure the signal-to-noise ratio (SNR) of a FM broadcast station. 1
16:47, 13 April 2024 MeasureFmSignalPower.jpg (file) 365 KB This is a flowgraph that will calculate the signal-to-noise ratio (SNR) of a FM broadcast station using a RTL-SDR. This flowgraph demonstrates both measuring signal power and use of the '''Complex to Mag^2''' block. 1
01:45, 13 April 2024 PhaseShiftDemo.grc (file) 8 KB This is the GRC file used to demonstrate the Phase Shift block. 1
19:24, 12 April 2024 Phase-shift-demo-display.png (file) 62 KB This is the time domain (left) and constellation (Argand) diagram showing the phase shift of a complex sinusoid. The phase has been shifted +125 degrees (3π/4 radians). 1
18:17, 12 April 2024 PhaseShiftDemo.jpg (file) 198 KB Demonstration of the "Phase Shift" block using a time domain (time sink) and constellation diagram. 1
