:MATH<n> Commands
The :MATH<n> commands are used to set various math operation function of the waveform between
channels.
Note:
 The math operations include the following types:
arithmetic operations: A+B, A-B, A× B, A/B
spectrum operation: FFT
Logic operation: A&&B, A||B, A^B, !A
function operation: Intg, Diff, Sqrt, Lg, Ln, Exp, Abs, AX+B
digital filter: Low Pass Filter, High Pass Filter, Band Pass Filter, Band Stop Filter
 For the logic operation, the waveform data involved in the operation and the preset threshold are
compared with each other, and then transferred to 0 or 1. Therefore, the operation results are only
reduced to 0 and 1.
