Designated frequencies
| Noise Reduction (NR)
Received signals become audible, emerging
from mixed noise, because the spectrum of
the periodic signals is enhanced while random
signals such as noise are attenuated. Signal
processing is adjustable in 256 steps, allowing
the most audible conditions to be set. The NR
feature is also very effective for such noise which
the previous noise blanker has not been able
to handle.
Beat Canceller (BC)
Completely periodic signals such as beat sounds
are exalted and cancelled. However, voice
signals are not processed as periodic signals
in this BC, but processed to be free from distortion.
Signal processing can be set in 256 steps to
achieve the most effective condition. The BC
is also effective for multiple beats.
Noise Blanker (NB)
Like the previous noise blanker, this NB detects
noise amplitudes and removes noise depending
on the amplitude level on the time axis. NB1
(narrow blanking width) and NB2 (wide blanking
width) can be switched over, and the
