Jul 1 2000

• Results from filtering code with white gaussian noise (gziped binary xmgr files for Solaris-Sparc). Graphs show the signal to noise ratio squared against time (shown as segment point number) as described in the notes. Sample rate 2048 Hz, 4096 points in data segment, variance of noise 64.0 unless otherwise stated. Filter output:
  
  
  • averaged over different numbers of data segments
  • for different sample rates
  • for different variances of gaussian noise
  • for four different runs with 65536 points in a data segment
  • with 65536 points in a data segment with results from four segments
