■Operation example of the frequency response filter
The following is an example when each filter is applied to the synthetic wave (2) which consists of three waves shown in the
composed wave (1).
In the following figure, the horizontal axis indicates time and the vertical axis indicates amplitude.
*1 The following is an example of an operation. The actual results may vary.
(1)
Filter type
Low-pass filter
High-pass filter
Band-pass filter
Band elimination filter
●Low-pass filter
A low-pass filter reduces and terminates signals with frequencies higher than the frequency specified to the cutoff frequency 1
(fCutoffFreqHz1) to pass only low frequency signals.
●High-pass filter
A high-pass filter reduces and terminates signals with frequencies lower than the frequency specified to the cutoff frequency 1
(fCutoffFreqHz1) to pass only high frequency signals.
Feature
Attenuates and terminates signals with frequencies higher than the specified frequency to pass only low
frequency signals.
Attenuates and terminates signals with frequencies lower than the specified frequency to pass only high
frequency signals.
Passes only signals with frequencies within the specified range.
Eliminates frequency signals within the specified range.
