Signal Conditioning

In a noisy environment it is very difficult for very small signals received from sensors such as thermocouples and strain gauges (in the order of mV), to survive without the sensor data being compromised. Therefore we need

• Amplification

• Regulator

• Attenuation

• Multiplexing

Following are the function of signal conditioning EXCEPT,

• Signal Level and Bias Change

• Convertions

• Filtering

• Rectifying

• Linearization

• Band Reject Filter

• RC Filter

What filter does the figure shows?

• Low Pass Filter

• High Pass Filter

• Band Reject Filter

• RC Filter

What kinds of operational amplifier does the figure illustrates?

• Voltage Follower

• Inverting amplifier

• Non Inverting Amplifier

• Differentiator

• Integrator

Low pass RC filter allows only low frequency pass through it and block the high frequency.

• TRUE

• FALSE
