Abstract
Systems and methods may receive data from a data interface of a base platform, convert the data into an analog signal and modulate the analog signal onto a direct current (DC) power line coupled to a connector of the base platform. Additionally, the modulated analog signal may be received from a DC power line coupled to a connector of a tablet platform, wherein the modulated analog signal is converted to a digital signal and demodulated to recover the data. In one example, the data includes user input data associated with an input device including one or more of a mouse, a keyboard, a keypad or a touchpad.

(canceled)
A data generation platform comprising:
- a data interface;
- a power port;
- a low pass filter coupled to the power port;
- a direct current (DC) power line coupled to the low pass filter;
- a connector coupled to the DC power line;
- a high pass filter coupled to the DC power line;
- and
- an embedded controller coupled between the data interface and the high pass filter, the embedded controller including:
- a converter to receive data from the data interface and convert the data into an analog signal, and
- a modulator to modulate the analog signal onto the DC power line via the high pass filter.
A method of processing data, comprising:
- receiving data from a data interface of a platform;
- converting the data into an analog signal;
- and
- modulating the analog signal onto a direct current (DC) power line coupled to a connector of the platform,
- wherein the data is converted to the analog signal by a converter connected between the data interface and a high-pass filter.
A method of processing analog signals, comprising:
- receiving a modulated analog signal from a direct current (DC) power line coupled to a connector of a platform;
- converting the modulated analog signal to a digital signal;
- and
- demodulating the digital signal to obtain data,
- wherein the modulated analog signal is converted to the digital signal by a converter connected between a data interface and a bandpass filter.
