Linear PCM Test Signals

The normal fading in and out of any Chirp
signal generates spurious frequency
components, leading to ripple in the
frequency response.
The Chirp sequences of the DR2 are
optimized for ripple of ± 0.2 dB maximum.
Chirp parameter combinations which would
result in higher ripple are automatically
corrected during input.
Delay Test
Characteristics and use
The Delay Test signal is a specially configured Chirp signal. In
combination with the “Acoustilyzer AL1“ or “XL2“ from NTi
Audio, it makes it possible to determine acoustic signal propa-
gation delay times. You can find further information in the hand-
books for the AL1 Acoustilyzer or XL2.
