A first device comprises at least one amplifier. The at least one amplifier is configured to receive a plurality of sensor signals from a plurality of sensors. The at least one amplifier is configured to amplify at least two of the sensor signals to generate a plurality of amplified signals. Each of the amplified signals corresponds to one of the sensor signals. The first device comprises a plurality of modulators. Each of the modulators is configured to modulate one of the amplified signals to a distinct center frequency through employment of a Voltage Controlled Oscillator (VCO) to generate a modulated signal. The first device comprises an adder configured to create a composite signal. The composite signal comprises the modulated signal from each modulator. The composite signal is configured for transmission to a second device.
