Abstract: A system for bidirectional signal transmission may comprise a forward data transmission circuit to unidirectionally transmit a first input signal and a backward data transmission circuit to unidirectionally transmit a second input signal. The backward data transmission circuit may comprises a logic circuit to detect a voltage difference over a resistance element in the forward data transmission circuit. When the voltage difference is lower than a threshold value, the logic circuit outputs a first voltage level. When the voltage difference is greater than or equal to a threshold value, the logic circuit outputs a second voltage level different from the first voltage level.

Abstract: An electronic device includes a waveform generator, a comparator, and an amplifier. The waveform generator receives a voltage from a power supply to the electronic device and outputs a voltage waveform signal. The comparator compares an input signal and the voltage waveform signal to output a first pulse-width-modulated signal. The amplifier receives the first pulse-width-modulated signal and outputs a second pulse-width-modulated signal.
