Question

The reason for a DAS to provide excitation is to

(check all that apply)
a.) provide power source for a sensor.
b.) check to verify the sensor is working correctly
c.) remove high frequency noise from the analog signal
d.) make sure the sensor power is extremely low noise and accurate
e.) filter out noise from the signal before the ADC

Answer 1

A DAS provides excitation to a sensor to provide power, remove noise, and ensure accurate measurements.

Step-by-step explanation:

The reason for a DAS (Data Acquisition System) to provide excitation is to:

• a.) provide power source for a sensor.
• c.) remove high frequency noise from the analog signal.
• d.) make sure the sensor power is extremely low noise and accurate.

By providing power to the sensor, the DAS allows the sensor to function properly and generate a signal. Additionally, the DAS can help filter out high frequency noise from the signal to ensure accurate data collection. Finally, the DAS ensures that the sensor power is steady and precise, minimizing any noise that may affect the readings.
