He first defines the switching function
and its properties together with the voltage and current relationships of basic switched circuits and applies the technique to construct PWM (pulse width modulation) signals representing sine waves or composite modulating signals.
Remote management of the switching function
is available through an RS-232 serial port on the rear panel.
But there are obstacles to this, one of them being that the switching function
of the new superconductors might have more thermal background "noise' because it is cooled at a higher temperature than are conventional superconductors.
An integrated switching function
allows tripped circuits to be immediately switched back on, as well as doubling as an ON/OFF switch.
