Pulses of less than 2/fc [s] are eliminated as
noise. Pulses of 7/fc [s] or more are considered
to be signals. In the SLOW or the SLEEP mode,
pulses of less than 1/fs [s] are eliminated as
noise. Pulses of 3.5/fs [s] or more are consid-
ered to be signals.
Pulses of less than 15/fc or 63/fc [s] are elimi-
nated as noise. Pulses of 49/fc or 193/fc [s] or
more are considered to be signals. In the SLOW
or the SLEEP mode, pulses of less than 1/fs [s]
are eliminated as noise. Pulses of 3.5/fs [s] or
more are considered to be signals.
Pulses of less than 7/fc [s] are eliminated as
noise. Pulses of 25/fc [s] or more are considered
to be signals. In the SLOW or the SLEEP mode,
pulses of less than 1/fs [s] are eliminated as
noise. Pulses of 3.5/fs [s] or more are consid-
ered to be signals.
Pulses of less than 7/fc [s] are eliminated as
