This chapter serves as an introduction to the book “Coaxial Electrical Circuits for Interference-Free Measurements”. It provides a discussion on interactions between circuits and eliminating electrical interference.

Chapter Contents:

• 1.1 Interactions between circuits - eliminating electrical interference
• 1.1.1 Basic principles
• 1.1.2 An illustrative example - using a phase-sensitive detector
• 1.1.3 Diagnostic equipment
• 1.1.4 Isolation
• 1.1.5 Totally isolating transformers and power supplies
• 1.1.6 Isolating a noisy instrument
• 1.1.7 The available methods for isolating outputs
• 1.1.8 Balancing
• 1.1.9 Minimising the effects of insufficiently isolated commercial instruments
• 1.1.10 The 'traditional' approach to DC and low-frequency circuitry versus the current-balanced conductor-pair coaxial approach
• 1.1.11 Thermoelectric emfs
• 1.1.12 Designing temperature-controlled enclosures
• 1.1.13 Ionising radiation (cosmic rays, etc.)
• 1.1.14 Final remarks
