... in the transmission lines. The transmission voltage used is limited to the inverter voltage unless a transformer is applied at the power source. With a series circuit, the coil voltage is a function of the Q value of the circuit and can be quite high, necessitating the use of high-voltage capacitors for tuning...

.... The first induction heaters sold by General Electric during World War II had rectifier tubes for the conversion of the alternating current (ac) to direct current (dc). Output control and tuning were accomplished through a combination of different taps on the output of the tank coil and a control knob...

This time-varying capacitance becomes the electrical signal that can be digitized and eventually converted back to sound with a speaker. Because of their low cost, small size...
