Sometimes the need arises to construct a really simple oscillator. This could hardly be simpler than the circuit shown here, which uses just three components, and offers five separate octaves, ...

This Design Idea demonstrates a simple way to generate a multiphase clock signal, the frequency of which can be varied with minimal change in phase shift(s). The phase shift of the second output can ...

Sometimes the best projects are the simple, quick hits. Easily designed, fast to build, and bonus points for working right the first time. Such projects very often lead to bigger and better things, ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a regenerative receiver, or maybe a direct conversion design, ...

Figure 1: Superconducting qubit–oscillator circuit. Figure 3: Selection rules and transmission spectrum around the symmetry point. In conclusion, we have experimentally achieved deep strong coupling ...

Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...
