ABSTRACT:
An analog signal is provided to a transistor circuit which shapes the sig to enhance the high frequency components thereof. An LED receives the enhanced signal so that a normally degraded light signal from an LED is compensated for thereby generating light signals that correspond with the original analog input. Fiber optics connect the LED to a receiver circuit, that detects the light communicated across fiber optics, and reconverts them to an electrical signal corresponding to the original analog input signal at the transmitter.
