The circuit is a triangle waveform generator that uses as few parts as possible. A 555 timer IC, 2 resistors and two capacitors make the triangle wave. The IC is connected in a 50% duty-cycle astable ...

Analog circuits are a historical and yet still effective way to develop waveforms and process signals, and are used for function generators, triangle-wave generators, absolute-value detectors, and ...

The field of wave digital modeling has emerged as a robust framework for simulating nonlinear audio circuits with high fidelity, bridging the gap between analogue intricacies and digital efficiency.

Talk about precision. New measurements of key wavelengths of ultraviolet light---down to a few millionths of a nanometer---are among the most precise ever reported and are improving calibrations of ...

Phase instability of the electricity supply to a television studio or O.B. centre causes transient changes in the repetition frequency of frame-synchronising pulses emerging from the waveform ...
