GEN18 — Writes composite waveforms made up of pre-existing waveforms.
Writes composite waveforms made up of pre-existing waveforms. Each contributing waveform requires 4 pfields and can overlap with other waveforms.
size -- number of points in the table. Must be a power-of-2 plus 1 (see f statement).
fna, fnb, etc. -- pre-existing table number to be written into the table.
ampa, ampb, etc. -- strength of wavefoms. These are relative strengths, since the composite waveform may be rescaled later. Negative values are permitted and imply a 180 degree phase shift.
starta, startb, etc. -- where to start writing the fn into the table.
finisha, finishb, etc. -- where to stop writing the fn into the table.
f 1 0 4096 10 1 f 2 0 1025 18 1 1 0 512 1 1 513 1025
f2 consists of two copies of f1 written in to locations 0-512 and 513-1025.
