Our digital receivers implement the future: Signal processing on frequency (spectrum) based level. Filtering and demodulation by directly using the spectral lines of a multiple faster and more precise transformation than the commonly used FFT! No Aliasing, no windowing, no picket fence effect, no secondary resonances. 2.5 Hz resolution without interpolation with 10 Spec/sec. Audio processing at 40 Hz/Bin with 160 fps.
