Difference Frequency Distortion (DFD) signal is described in the standards IEC60118 and IEC60268. It consists of two pure tones: 12460 Hz and 12540 Hz and is useful for assessment of intermodulation distortion. % DFD 12.5 kHz mean, 80 Hz difference (12460 Hz + 12540 Hz) % 30s, -10 dBFS (rms), Stereo (L=R), 44100 Hz, 16 bit Fs = 44100; % [Hz]

Here are a few basic signals: Unit Step Function Unit step function is denoted by u (t). It is defined as u (t) = { 1 t ⩾ 0 0 t < 0 It is used as best test signal. Area under unit step function is unity. Unit Impulse Function Impulse function is denoted by δ (t). and it is defined as δ (t) = { 1 t = 0 0 t ≠ 0 ∫ − ∞ ∞ δ ( t) d t = u ( t)
