Most sensors needs some signal conditioner electronics before digitize the signal.
|
|
Few examples are:
|
|
|
|
- Piezoelectric force sensors
|
|
- Geophone
|
|
- Photodiode
|
|
- Thermocouple
|
|
|
|
The signal conditioning electronics can have different functions:
|
|
|
|
- Amplification
|
|
- Isolation
|
|
- Filtering
|
|
- Excitation
|
|
- Linearization
|
|
|
|
Depending on the electrical quantity that is meaningful for the measurement, different types of amplifiers are used:
|
|
|
|
- Current to Voltage ([Transimpedance Amplifiers]({{< relref "transimpedance_amplifiers" >}}))
|
|
- Charge to Voltage ([Charge Amplifiers]({{< relref "charge_amplifiers" >}}))
|
|
- Voltage to Voltage ([Voltage Amplifier]({{< relref "voltage_amplifier" >}}))
