incr is a value or expression used with the optional step keyword to define the
size of the loop count increment steps. By default the loop counter increments in
steps of 1. The incr can be a negative value in which the loop count decrements
steps. The increment value is a real or integer number.
. Although the start, end, and incr arguments accept real numbers, their
values are rounded off to the nearest integer value.
expr is one or more equation expressions that are executed when the for loop
condition is true.
for i = nsht to (size – nsht –1) step 1
sp = i – nsht
ep = i + nsht
”TEMP1.WFM” = extract(”NOISE.WFM”, sp, ep)
”TEMP2.WFM” = ”TEMP2.WFM” / nump
next
Hpf( )
The hpf() statement creates a new file by passing the specified waveform file
through a high-pass filter.
Waveform
”output_filename” = hpf(”filename1”, cutoff_freq, taps, atten)
”output_filename” is the complete file name (file name and extension) to contain
the filtered waveform data. The argument can include a relative or absolute path
name. Enclose the file name within double quotation marks.
”filename1” is the complete (file name and extension) name of the source file for
the high-pass filter operation. The file must be on the active drive. The argument
can include a relative or absolute path name. Enclose the file name within double
quotation marks.
cutoff_freq is the high-pass filter cutoff frequency. You can enter the value as a
real or scientific notation number. You can also enter the value as an expression
that resolves to a valid number.
taps is the number of delay elements that composes the digital filter. The range
of taps is 3 to 101. You must enter the integer value as an odd number.
