| Sinusoidal waves are important in electronics. Many applications need sinewaves to function and a lot of electronic circuits can be tested b...
| The diagram shows how a three-phase sine wave oscillator can be built with a single Type UAF42 state-variable filter and some resistors an...
| As the title implies, the present circuit is intended to convert sinusoidal input signals to TTL output signals. It can handle inputs of...
| This circuit converts a serial pulse train into a sinusoidal output voltage consisting of 30 discrete steps. The 4-bit output of up/down...
| Micro Linear's ML2035 monolithic programmable sine wave generator IC is used here without the usual microcontroller to supply the frequenc...
| A circuit is described that, controlled by a computer, generates perfect sine wave signals.
| Oscillators exist in a bewildering number of types and variants, each with its own, specific, features. A type known for its near-perfect s...
| This series is intended to help you with the quantitative aspects of electronic design: predicting currents, voltage, waveforms, and other...
