Variable Capacitors

Variable Capacitors
Variable capacitors have capacitance values that can be varied by applying voltage to their electrodes.

Regarding Continuous and Polling


Continuous means that the specified voltage is continuously applied for Port1,2.

sa


Polling means that the specified voltage is switched on and off and
applied for port1,2.(on: 40msec, off: 360msec)
