Signal Conditioning

Converts a physical phenomenon into a measurable electrical signal? What is this device?

___________detect the physical variations that happen in the surroundings.

Analog signal can have infinite number of values and varies ________with time.

• continuously

• definitely

• infinitely

• repeatedly

_______ is the separation of a circuit from other sources of electrical potentials

• Electrical isolation

• Filtering

• Excitation

• Linearization

Some signals are named after their specific shapes -

• sine

• square

• sawtooth

• triangle

• All the these

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

• Filtration

• Attenuation

• Multiplexing

• Filtration First then

  Amplification

Strain gauges, thermistors and RTDs, for example ______external voltage or current excitation signals

• require

• do not require

Flux sensors and thermocouples ______ excitation

• require

• do not require
