MLS (Maximun Length Sequence)
•Continuous, periodic, wide-band signal with white-like spectrum (shift register and XOR port), fast (real-time) & easy IR deconvolution by Hadamard Fast Transform algorithm.
Linear & Logarithmic sine sweeps
•signals in which the frequency increases or decreases linearly or exponentially with time.
Features
•Good Signal-to-Noise ratio (SNR).
•Possibility to pre-compensate for transducer’s response.
•Possibility to create an excitation signal with arbitrary spectrum.
