Abstract:
Apparatus and associated methods relating to the amplification of an audio signal. In particular, such application is performed by using an audio to pulse train converter configured to convert an analog audio signal to a complementary train of pulses having a duty cycle indicative of the level of the analog audio signal. The audio to pulse train converter can be a class-D amplifier, a sigma-delta amplifier, self-oscillating amplifier, or any other audio amplifier that is configured to provide complementary pulse trains each having a duty cycle that is representative of the input audio signal. The complementary pulse trains are directed to a circlotron that is configured to provide an amplified version of the audio signal at two output nodes. The amplifier circuit may further include one or more low pass filters and/or output reference resistors. Two similar circuits can be configured together to provide stereo audio amplification.

Claim (Index 13):
The method of  claim 12 , wherein the first and second high frequency triangle wave signals have a frequency at least ten times a highest frequency component of the analog audio signal.
