Discrete Fourier Transforms are calculated to estimate noise phase and amplitude. The estimated noise is subtracted from the trace in the time domain. It has been rewritten to analyze a window of data from t1 to t2 and then to apply it to the whole trace Usage: Input: datain : Input data freq1 : Start scanning at this frequency (Hz) freq2 : Upper frequency limit (Hz) inter : Frequency step (Hz) such that ((freq2-freq1)/inter) is a multiple of 10 t1 : Start time of window (seconds) t2 : End time of window (seconds) Output: dataout : Output data Example : This is what I use to remove 60 Hz noise filtered = harmon_new(data,59.88,60.12,0.01,0,0.5); Reference: http://www.cg.NRCan.gc.ca/staff/adam/software/monofreq.html Warning: Program does not check for reasonable parameterswritten by: Erick ADAMDec. 1995Rewritten by Marko Mah February 1999</pre><HR><H3>Cross-Reference Information</H3>This function is called by<pre><UL><LI><A HREF = "../5.demos2/demoproc1.html">demoproc1</A> ./demos2/demoproc1.m</LI></UL></pre><HR>Produced by <A HREF = "http://www.nd.edu/Courses/kantor/matlab/mat2html">mat2html</A> on Wed Jun 14 15:21:32 Canada/Eastern 2000<BR>Cross-Directory links are: ON<BR></BODY>⌨️ 快捷键说明
