Information
The Model
4-NB is a solid-state noise blanker for
use with the R-4C Receiver. Unlike noise clippers
or limiters commonly found in communications
equipment, the
4-NB is an advanced noise blanker
which actually mutes the receiver for the duration
of the noise pulse. Between noise pulses, full
receiver gain is restored.
Receiver AGC is affected
only by the desired signal and not by noise. The
4-NB is most effective on strong, periodic impulse
noise such as ignition noise. It is least effective on
random noise. Random noise is continuous in time
and the information it masks cannot be recovered
by either blanking or limiting techniques.
