Operation Manual

6.104 Xor 162
The Volume module is used to adjust the amplitude of a signal. It has one input
and one output. The output signal is the input signal multiplied by a constant varying
between 0 and 2 (+6dB).
Typical Use
The Volume module is used whenever the level of a signal must be adjusted. A
Volume is usually placed just before an Audio Out module (see Figure 29.
The default values of the following parameter is set at construction
• gain: default value of the volume gain (value between 0 and 2).
6.104 Xor
The XOR module performs an XOR logic operation. The one output of this module is either 1
(true) or 0 (false) depending on the values sent to the two inputs. To deliver 1 at the output, To
deliver 1 at the output, only one of the two inputs must receive a value of 1, otherwise the output
will deliver a value of 0. This module has no front panel. The following diagram shows the output
value depending on the values in the two inputs. Input signals are considered False (0) when smaller
