DOLBY В AND C NOISE REDUCTION SYSTEM
The Dolby noise reduction system substantially reduces the tape
background noise (hiss) inherent in the cassette medium. Dolby B NR is
most widely in use. However Dolby C NR is a much more recent
development and represents significant improvements over Dolby B
NR.
Tápe background noise consists primarily of high frequency informa
tion, which is particularly annoying during soft passages. The Dolby NR
system increases the level of low volume mid- and high-frequency
signals during recording and reduces the level of these signals by an
identical amount during playback. As a result, the playback signal is
identical to the original source, but the level of background noise
generated by the tape is greatly reduced.
The operating principle of Dolby C NR is similar to that of Dolby
8
NR
except for the encoding/decoding response curves. The noise reduc
tion effect obtained with Dolby C NR is up to 20 dB, compared to 10 dB
with Dolby B NR. In addition, Dolby C NR uses an anti-saturation
network and spectral skewing circuitry for a significant improvement in
the dynamic range of the mid- to high-frequencies.
