ShFilter
v1 v2 14 14 Kind of filter. Valid values are 15 15 * 'F' - applies FFT filter, previously read in by a "[ShFili FILI] F <file>" command 16 * ' D' - applies digital filter, previously read in by a "[ShFili FILI] D<file>" command16 * 'T' - applies digital filter, previously read in by a "[ShFili FILI] T <file>" command 17 17 * 'R' - applies recursive filter, previously read in by a "[ShFili FILI] R <file>" command 18 18 * 'A' - attenuation with t* = <att> sec 19 19 * 'H' - computes Hilbert transformation 20 20 * 'M' - computes minimum delay wavelet 21 * 'P' - (undocumented) 21 22 22 23 * <trc-list> ''parameter type: trace list''[[BR]] … … 34 35 Valid only for FFT and digital filters. Applies a cosine taper to filtered trace in frequency domain. <tapval> ranges from 0.0 to 1.0. Default value is 1.0. The taper is started at sample <tapval>*N if N is the length of the trace in frequency domain. A value of 1.0 and greater means that no taper is applied. 35 36 37 * /demean[[BR]] 38 (undocumented) 39 40 * /lpc[[BR]] 41 (undocumented) 42 36 43 === example === 37 44
