Syntax

th_cfc(xvect, yvect, class, octave, debug_flag)

Arguments

xvect
The time vectors (seconds).
yvect
Response vectors to be filtered (any units).
class
Can be 60, 180, 600, or 1000.
octave
Can be 3 or 6.
debug_flag
Optional argument. Flag to turn on debug mode (points to message log). Default is off.

Example

th_cfc(p1w1c1.x, p1w1c1.y, 1000, 6)

Comments

Channel Frequency Class filter is a low-pass filter, which means that high frequencies are filtered.

Equivalent filters in TH++ are:
  • LOW PASS CFC 60 (-3dB)
  • LOW PASS CFC 180 (-3dB)
  • LOW PASS CFC 600 (-3dB)
  • LOW PASS CFC 1000 (-3dB)
  • LOW PASS CFC 60 (-6dB)
  • LOW PASS CFC 180 (-6dB)
  • LOW PASS CFC 600 (-6dB)
  • LOW PASS CFC 1000 (-6dB)
