8.2.1 Setting Sample
Select a sampling device from the
Sampling Device
pull-down list on the
Sample Setting
interface (Figure 8-2).
Sampling Port can be set to a value from COM0 to COM9.
8.2.2 Setting Filter
Set filters on the sample setup interface (Figure 8-2).
DFT Filter
DFT filter greatly reduces the baseline fluctuations without affecting ECG signals. There are two
options:
Weak
and
Strong
.
Note
: If DFT filter is set to
Strong
, the ECG data displayed on the screen is 0.85 seconds
later than the real-time ECG data; if DFT filter is set to
Weak
, the ECG data
displayed on the screen is 1.8 seconds later than the real-time ECG data.
EMG Filter
EMG filter suppresses the disturbance caused by strong muscle tremor. The cutoff frequency can
be set to
25Hz
,
35Hz
, or
45Hz
.
Lowpass Filter
Lowpass filter
restricts the bandwidth of input signals. The cutoff frequency can be set to
75Hz
,
100Hz
or
150Hz
. All the input signals whose frequency is higher than the setting cutoff
frequency will be attenuated.
AC Filter
AC filter suppresses AC interference without attenuating or distorting ECG signals. There are two
options:
50Hz
and
60Hz
.
