The experiments in this Locktronics solution are designed for the more advanced students of electronics who need to understand the theory and practice of a wide range of electronic components and circuits, from basic diode circuits through to feedback and oscillator design.

Learning objectives include:

• Semiconductor devices: diodes, zener diodes, transistors, photodiodes, thyristor, voltage regulator, operational amplifiers.  Semiconductor circuits: Full and half wave rectifiers, transistors as switches and amplifiers
• Amplifiers: characteristics, power amplifiers (A, B, AB), inverting, non-inverting, tuned, integrator, differentiator, comparator, Schmitt, filters (high pass, low pass, band pass, notch)
• Amplifiers with feedback
• Oscillators: Wien bridge, twin T, RC ladder, LC coupled, crystal
