This GNU Radio Companion flowgraph uses a Signal Source to generate a 1 kHz sine wave, processes it with a Log Power FFT block (FFT size 1024, reference scale 512, FFT Shift on) to compute a logarithmic power spectrum, and displays the result in a QT GUI Vector Sink, showing a peak at ±1,000 Hz at 0 dB.

The setup is straightforward, and the output aligns with the expected behavior of the block as described. Flowgraph Components and Configuration. Signal Source Generates a sine wave. Frequency: 1 kHz. Sample Rate: 32,000 samples per second (32 kHz). Amplitude: 1 (a simple, clean input signal). Throttle Block... |
