Abstract:
1. A method for transmitting analog audio signals using electro-optic radiation without degradation of modulation further comprising; powering circuit with low-voltage alternating current, receiving an analog signal from a device creating differentiating current, blocking to prevent backflow of current and to protect circuitry from voltage spikes, biasing voltage from said powering circuit input into operational amplifier, slewing changes in analog current levels into discrete voltage levels while using capacitance to maintain sinusoidal signal, controlling output within linear range of circuit using feedback, adjusting gain of voltage output through use of feedback and gain resistors, softening power to protect against said voltage signal from being outside of supply rail parameters of operational amplifier, converting electrical voltage into electro-optic radiation by using a diode, adapting said diode to transmit electro-optic radiation by transforming covering of diode to a flatness that will accept opening in transmission channel, transmitting electro-optic radiation through said transmission channel, receiving and amplifying electro-optic radiation whereby output voltage modulates linearly with intensity of electromagnetic radiation, adjusting gain while increasing responsivity, reamplifying voltage from said receiving and amplifying step, biasing voltage, isolating AC voltage from DC power circuits, while transferring voltage values through photo-transistor output, increasing voltage through Darlington pair circuitry, creating electro-optical radiation corresponding in strength to applied voltage, igniting florescent fiber optics using said electro-optical radiation and sending analog signal to output device.
