There are times when one needs to take an digital signal and create the inverse of this signal. Doing this in discrete components can be challenging to fit into a small space. Lucky for us there are ...

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 ...

Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses ...
