A special frequency determined by the values of the resistance, capacitance and inductance refers to the resonance in AC circuits. The resonant frequency point occurs where the inductive reactance of ...

A quartz crystal's case will be stamped with the devices' rated operating frequency, but that number is only an approximation to the real story which is that there is more than one crystal resonant ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...
