Filtering Processing

If there is much interference in the signal curve, the filtering processing method can be adopted; in “a-ε”, “F-ε” and other tab interfaces, click the left mouse button to select a curve and enable the channel background to change to light blue, which means that this curve is considered as the signal curve to be processed. And then conduct adjustment and processing for the curve until satisfaction through the filtering, zeroing, rotation zeroing and other functions in the menu or toolbar.

If the signal curve is good, this operation step can be omitted.

Sampling interface	Analysis interface

High-pass filter, low-pass filter

The objective of high-pass filtering and low-pass filtering is to analyze and further process the acquired signals.  After analyzed and further processed, the acquired waveforms should be smooth and less interfered, so that reflected waves of defects and the bottom of the pile can be clearly distinguished. 

Click on the "high-pass filter” and “low-pass filter” respectively to enter their input dialogue boxes (Figure 7).  The input dialogue boxes are slightly different but similar.  Click on "OK" after inputting, then the acquired signal waveform will be processed base on the selected value, and the processed signal waveform will be displayed in the waveform display area.  Otherwise click on "Cancel" to give up such processing and keep the original signal waveform in the waveform display area.  Input range: 1—10000.  

E+、E-

The objective of adjusting the exponential amplification is to preprocess the acquired signals.  After preprocessed, signal of the bottom of the pile can be clearly shown, without any clipping of the signal of the top of the pile.  

Note: Sometimes the exponent is amplified so much that the waveform is distorted, thus the defects of the deep pile will be exaggerated.  

Click on "E +" to exponentially amplify the signal waveform in the waveform display area step by step.  The amplified value is shown behind “"X" icon in the schematic diagram are of the pile, wherein such schematic diagram area of the pile locates below the signal waveform.  Click on "E-" to exponentially compress the signal waveform in the waveform display area step by step.  The final compressed value is also shown behind "X" icon in the schematic diagram are of the pile. 

When the analysis process is done, click on "exit" in the lower left corner of the analysis screen to return to the data acquisition screen and prepare for the next signal acquisition.
