There the effects are brought about by the high frequency impressed.
A high frequency, a most peculiar and most powerful interrupter.
Direct current is sent into the wire through a complicated wire system and generates a high frequency current of tremendous power.
The whistles high frequency waves also awakened Cerberus, the three-headed watch dog, besides actuating The Dingus.
The skin responds to pressures, the ear to vibrations of high frequency; the lateral line is between the two in its function.
Where high frequency currents surge in a circuit the inductance of it becomes a powerful factor.
High frequency currents make use of the heating effects of the currents.
A high frequency current will surge in a wire which is open at both ends like the aerial.
When fitted with a spark gap the high voltage, low frequency currents are converted into high voltage, high frequency currents.
The impedance these windings offer to the high frequency of lightning oscillations is great.
