Figure 4 shows a schematic of the ZEN active control system. In addition to the DSP
board, the system includes a PC (with a dedicated user interface) to control the DSP
board over a USB link. The controller provides six inputs (three for the reference signals
and three others for the error signals). Each input can be designated via software as either
a microphone or a direct input. With the microphone input selected a bias is provided,
and a high pass filter at 16 Hz is activated. The control system includes three outputs for
the control signals. Figure 4 shows an acoustic example that includes six microphones
and three loudspeakers. However, the control system is generic and can be used with
other types of sensors and actuators.
