[Ideas For Design]
Electronic Flicker Pulsing Suppresses EMI Problems
Pulsing circuits generate EMI that can affect sensitive circuitry and adversely contribute to the spectral signature of the equipment. “Flicker-noise” concepts, derived from chaos theory, have been employed to efficiently pulse circuitry while... — Contributing Author

[Ideas For Design]
Vocal-Aural Feedback Digital Delay Device
When humans speak, many complicated, interrelated, and not completely understood neural and muscular processes must all coordinate. Most of these processes aren’t accessible to simple investigation, but one important speech-production mechanism is... — W. Stephen Woodward

[Ideas For Design]
Novel Decoding/Threshold-Sensing Technique
Here’s an Idea For Design that’s more Idea than it is Design. Using inexpensive memory devices, you can construct a voltage, current, or count sensing system that can be permanently programmed for one set of input conditions or... — Contributing Author

[Ideas For Design]
Simple Current Sensor Features Galvanic Isolation
Applications that require a simple, low-cost current sensor with galvanic isolation can employ the circuit described here. If used as drawn, it's possible to sense currents up to 10 A with high precision (usually within %) and wide bandwidth (more... — Contributing Author
