The reactance tube modulator shown in the Figure uses a remote cut-off tube whose transconductance g m varies from 2500 µS to 3500 µS (in the SI metric system, the unit of conductance is the siemens, ...

In the December 2008 issue of EC&M, we talked about calculating the inductive reactance of conductors that are in close proximity to (or touching) one another. We also noted that the inductance and, ...

If you’ve dealt with reactance, you surely know the two equations for computing inductive and capacitive reactance. But unless you’ve really dug into it, you may only know the formula the way a school ...
