Parameter: Rectifier baseline

Full name: Baseline level for full-wave rectification
Units: V or A/D
Range: [ -32768 A/D, 32767 A/D ]
Initial value: -32768 A/D

Affects: Filter operation

To obtain the linear envelope of a signal, you have to full-wave rectify the signal, then low-pass filter it with a relatively low cutoff frequency. To do this, enable the "Rectify before filtering" option, set this parameter to the level where the signal is to be "folded over" by full-wave rectification, and set the filtering parameters.

This parameter can be set visually, using the pointing device to set the level.
