Signal navigation
Introduction to the signal browsing with the Signal Analyzer from FFT Properties.
Marking the signal and scaling the axes
Learn how to measure the time signal — max, min, frequency between peaks, distance between interpolated zero-crossings — and different strategies for scaling the axis.
Converting a signal from any format
Extract the audio track from a video file and convert any audio file to text format. Cut and copy is also possible.
Signal playback
The signal analyzer has amazing flexibility when it comes to playback of arbitrary signal sources. The sampling frequency of the source does not matter: any file can be played at any sampling frequency. Real-time linear-phase true-arbitrary-factor rate converters with perfect anti-aliasing deliver amazing results.
Signal generator
An introduction to the signal generator features. Generate a wide array of different signals and analyze the frequency response in real time.
Spectrum analyzer
Selecting the window and the spectral interpolation factor, real cepstrum, unwrapped phase, peak marking and filtering, and the averaged spectrum with confidence intervals.
Spectrogram analyzer
Here we explore the features of the 2D and 3D spectrogram: signal selection, spectrogram navigation, scaling, colour palette selection and more.
Digital filtering
We explore two design methods for a linear-phase filter, and apply the designed filter to a time series.
