 EDF generator version 1.09 Copyright (c) 2020 - 2022 Teunis van Beelen   email: [email protected]

 Usage: edfgenerator [OPTION]...

 options:

 --type=edf|bdf default: edf

 --len=file duration in seconds default: 30

 --rate=samplerate in Hertz default: 500 (integer only)

 --freq=signal frequency in Hertz default: 10 (may be a real number e.g. 333.17)

 --wave=sine | square | ramp | triangle | white-noise | pink-noise default: sine

 --dcycle=dutycycle: 0.1-100% default: 50

 --phase=phase: 0-360degr. default: 0

 --physmax=physical maximum default: 1200 (may be a real number e.g. 1199.99)

 --physmin=physical minimum default: -1200 (may be a real number e.g. -1199.99)

 --amp=peak amplitude default: 1000 (may be a real number e.g. 999.99)

 --unit=physical dimension default: uV

 --digmax=digital maximum default: 32767 (EDF) or 8388607 (BDF) (integer only)

 --digmin=digital minimum default: -32768 (EDF) or -8388608 (BDF) (integer only)

 --offset=physical dc-offset default: 0

 --datrecs=number of datarecords that will be written into the file, has precedence over --len.

 --datrec-duration=duration of a datarecord in seconds default: 1 (may be a real number e.g. 0.25)
                   effective samplerate and signal frequency will be inversely proportional to the datarecord duration

 --signals=number of signals default: 1 in case of multiple signals, signal parameters must be separated by a comma e.g.: --rate=1000,800,133

 --merge  merge all signals into one trace, requires equal samplerate and equal physical max/min and equal digital max/min and equal physical dimension (units) for all signals

 --help

 Note: decimal separator (if any) must be a dot, do not use a comma as a decimal separator


 examples:

 edfgenerator --type=bdf --len=60 --rate=44000 --freq=1000 --wave=square --dcycle=15 --unit=V --offset=500 --physmax=5000

 edfgenerator --type=edf --len=30 --signals=5 --rate=1000,800,500,975,999 --freq=5,13,7,1,1 --wave=sine,square,ramp,pink-noise,white-noise --dcycle=50,25,75,50,50 --unit=uV,uV,uV,uV,uV --physmax=3000,3000,3000,3000,3000 --physmin=-3000,-3000,-3000,-3000,-3000 --datrec-duration=0.5

 merge 3 sine waves into one trace:

 edfgenerator --type=edf --len=30 --signals=3 --rate=1000,1000,1000 --freq=5,15,25 --wave=sine,sine,sine --unit=uV,uV,uV --amp=200,66.667,40 --physmax=3000,3000,3000 --physmin=-3000,-3000,-3000 --merge
