Signals from thermocouples are usually very weak. What is the main component used to amplify this signal?

• Band-Pass Filter

• Operational Amplifier (Op-Amp)

• Digital-to-Analog Converter (DAC)

• Analog-to-Digital Converter (ADC)

• Galvanic Isolator

The signal conditioner used to eliminate high-frequency noise from a signal is called:
