Designers of VCO modules can reduce the size and increase the performance of these modules with a new device that combines in a single tiny package the company's NE894 transistor for oscillator ...

While working on recreating an “ancient” (read: 60-year-old) logic circuit type known as resistor-transistor logic, [Tim] stumbled across a circuit with an unexpected oscillation. The oscillation ...

The circuit was created to produce an oscillator operating at low frequency for use in the production of electronic music and experimenting and testing tone controls. Oscillator – an electronic ...

Voltage-controlled oscillators (VCOs) are pivotal components in modern communications and signal processing, where their ability to generate a stable yet tunable signal is paramount. The performance ...

Sometimes, it is useful to transmit a low-power radio signal to create a beacon, to send a signal carrier to a near receiver, to transmit in QRP or QRPP mode, and so on. The circuit shown here is very ...
