Acoustic Measurement Systems
-
Even AuSIM's audio simulation is only as good as the model parameters within the simulation. For AuSIM, deriving optimal model parameters begins with studying the acoustic world around us. The AuSIM3Dtm display systems synthesize a virtual aural environment from parameters based on the physical world. But the same techniques can be applied to reverse the process and extract parameters from the physical world to use for later synthesis.

Shunt Voltage References
-
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.
