Title: Edgar Sexauer: Innovator in Audio Technology
Introduction
Edgar Sexauer is a notable inventor based in Stuttgart, Germany, recognized for his contributions to audio technology. With a total of four patents to his name, he has made significant advancements in the field of audio signal processing.
Latest Patents
One of his latest patents is focused on audio superpositioning. This innovative circuit enables the superpositioning of different audio signals, such as voice, music, or ringer signals, in an audio output device. The design allows for individual superpositioning to be activated and performed through a combination of resistors and switches, eliminating the need for an additional mixing amplifier. This approach reduces power consumption, minimizes the required chip area, and improves the power supply rejection rate (PSSR).
Another significant patent involves combining audio and ringing modes. This circuit utilizes the same amplifiers and volume adjustment circuitry for both the ringer and audio modes of a mobile phone. The volume adjustment is achieved through precise amplitude settings via gain control stages of an inverting voltage amplifier. This design avoids high power dissipation associated with pulse width modulation (PWM) and mitigates the risk of over-and undershooting of the amplifier's output signal.
