BSc Physics with Theoretical Physics / Course details

Year 2 Lab Work (One Semester)

Amplifiers and Feedback:

To understand how analogue signals may be amplified, manipulated and generated in a controlled manner, and how they may be interfaced to digital systems for subsequent processing.

Amplifiers and Feedback:

On completion successful students will be able to:

1. To learn the behaviour of an ideal amplifier under negative (positive) feedback.

2. To be able to apply this to simple amplifier, summer, integrator, phase shifters and oscillator.

3. To test the limitations of a real amplifier.

4. To describe basic methods of ADC (analogue-to-digital conversion).

Amplifiers and Feedback:

1. Elementary circuit theory – discrete components, Kirchoffs laws and complex analysis

2. Semiconductor amplifiers – real and ideal systems

3. Positive feedback, oscillators and control loops

4. Analogue-to-digital conversion

Lab:

During the conduct of the experiment, students will be able to ask questions and follow the experiment being conducted. Those working on remote experiments will have regular communication with their demonstrator.
 
During interviews, advice on how to improve the measurement, analysis and presentation of results will be given orally and also written on the assessment sheets, copies of which will be given to the student.
 
In written reports, detailed comments on how the report might be improved are written on the reports. More general comments are written on the marked sheets, copies of which are returned to the students along with the marked reports. Students are strongly encouraged to contact the markers, when any written comments can be elaborated upon.

Amplifiers and Feedback: Laboratory pairs will be allocated, and supported by, a demonstrator who will monitor progress and provide continuous feedback. Detailed feedback, with respect to the Learning Outcomes, will be provided after the assessment interview.
