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

Measurement Science: 7. Measurements instruments II

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: 6. Measurements instruments I

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: 5. Analog-to-digital convertors

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: 4. Instrumentation amplifiers

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: 3. Sensors readout and signal conditions

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.

Measurement Science: 2. Sensors

EE1320. Introduction to measurement technology and measurement systems. A general overview of concepts in the course is given. And important aspects such as calibration and measurement uncertainty are explained. The anatomy of the measurement system is also discussed, introducing the conversion of data acquisition to a usable output signal, and deviations which can occur in this transfer.
