    Measurement Science: 7. Measurements instruments II

    Measurement Science: 7. Measurements instruments II

    EE1320. When measuring the current, the amplitude of AC signals can be defined in several ways, and the basic principles of the oscilloscope are important. Time and frequency measurements are explained, as well as how a comparator can be used to remove amplitude information in these measurements.

    Measurement Science: 6. Measurements instruments I

    Measurement Science: 6. Measurements instruments I

    EE1320. Three types of measurement instruments are discussed: Voltage, current and resistance measurements. Concepts such as tracking errors, reflections and 4 vs. 2 point measurements are illustrated.

    Measurement Science: 5. Analog-to-digital convertors

    Measurement Science: 5. Analog-to-digital convertors

    EE1320. The basic principles of sampling and quantization in digital analog conversion is discussed, as well as three important ADC types: Direct (Flash ADCs), integrating(Dual-slope ADCs), compensating (Successively-approximating ADCs).

    Measurement Science: 4. Instrumentation amplifiers

    Measurement Science: 4. Instrumentation amplifiers

    EE1320. Before discussing how three opamps can be combined in a circuit to form an instrumentation amplifier, balance measurements (wheatstone bridge) and the importance of the common mode rejection ratio are explained.

    Measurement Science: 3. Sensors readout and signal conditions

    Measurement Science: 3. Sensors readout and signal conditions

    EE1320. Signal conditioning is needed to adjust the output signal of the sensor to the input of the Analog Digital Convertor. Opamps are discussed as suitable building blocks for sensor readout. However, their non-ideal properties influence the transfer.

    Measurement Science: 2. Sensors

    Measurement Science: 2. Sensors

    EE1320. Different types of sensors are discussed. Sensors allow transduction to the electrical domain, distinguishing between (self-generating /modulating) and (direct / tandem transduction). Types of sensors which are discussed are: resistive, capacitive, inductive, thermoelectric, piezoelectric, and semiconductors.
