Add
Add waveform data stored in a text file to the current waveform (displayed on the screen). The
resulting new waveform is automatically normalized by dividing the new waveform by 2. To look
at it differently, each amplitude value is weighted by a factor 0.5 before the add operation is
performed.
If the lengths of the two waveforms differ, the longer length is taken as the length of the new
waveform.
Subtract
Subtract waveform data stored in a text file from the current waveform (displayed on the screen).
The resulting new waveform is automatically normalized by dividing the new waveform by 2. To
look at it differently, each amplitude value is weighted by a factor 0.5 before the subtract operation
is performed.
If the lengths of the two waveforms differ, the longer length is taken as the length of the new
waveform.
Symmetry of waveform X-axis
Flip the current image around the X-axis to create a mirror image of the previous waveform.
Symmetry of waveform Y-axis
Flip the current image around the vertical center line, which divides the editing screen in half.
Amplitude Divide
Divide the amplitude of the current waveform by an integer value. The value can be positive or
negative (but not zero)
Amplitude multiply
Multiply the amplitude of the current waveform by an integer value. The value can be positive or
negative (but not zero)
Frequency multiply
Multiply the timebase value of the current waveform by an integer value. The value must be
positive (but not zero). An integer value of 2 will double the frequency
Formula of sine add
Add 2 sine waves according to the predefined formula 1*sin(x) + a*sin (b*x). Choose parameters a
and b. The first sine wave in the equation cannot be edited.
