• Thermal noise caused by the random motion of charged particles in the sensor and the amplifier.
• Electromagnetic noise from electrical equipment (e.g. computers) or communication devices.
• Shot noise from quantum mechanical events.

Effects of Noise
• Reduces accuracy and repeatability of measurements.
• Introduces distortion in sound signals.• Introduces errors in control systems.

What to Do?
How can we eliminate or reduce the undesirable effects of noise?
• Grounding/shielding electrical connections• Filtering (smoothing)• Averaging several measurements

Signal Bandwidth
Conceptually, bandwidth is related to the rate at which a signal changes:
High BW Low BW

Bandwidth and Sampling
A higher bandwidth requires more samples/second:
High BW Low BW

Bandwidth Limitations
Every component in the instrumentation system has bandwidth limitations:
• Sensors do not respond immediately to changes in the environment.
• The amplifier output does not change immediately in response to changes in the input.
• The A/D converter sampling rate is limited.

Amplifier Characteristics
Amplifiers are characterized in terms of attributes such as:
• Gain• Bandwidth and/or frequency response• Linearity• Harmonic distortion• Input and output impedance

Operational Amplifiers (OP AMP)
- They have differential inputs: output voltage is the amplified difference of two input voltages.
-They have very large gains (>103).
A commonly used type of amplifier
Their circuits can be designed to:
- Provide voltage gain or attenuation.- Convert current to voltage.- Integrate or differentiate. -Filter out noise or interference.

Feedback
When sensor output is used to control the system in a desired manner.
Example: Industrial Process Control
In many manufacturing processes (integrated circuits, for example) temperatures must be closely controlled.Feedback can be used to maintain a constant temperature.

Benefits of Feedback
• Provides stability with respect to changes in system parameter values.
• Helps to obtain a (nearly) linear response from non-linear components.
• Can be used to change the characteristics of a system under control.
