IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an ...

This article presents a single-channel, multifrequency simultaneous excitation system for Lamb wave-based damage imaging. First, a low-cost bandpass filter circuit module is used to divide the ...

A simple RC circuit can’t function as an inverter, but a previous tutorial explored how an RC circuit’s output behaves when driven by an exponentially damped RLC circuit, offering insightful ...
