Signal detecting and emitting device

摘要

Systems, methods, apparatus, and articles of manufacture are disclosed. An example playback device includes a signal detector adjacent to a first side of the playback device; a signal emitter adjacent to a second side of the playback device; a processor; and memory having stored thereon instructions executable by the processor to cause the playback device to perform functions. The example functions include detecting, by the signal detector, an analog signal; amplifying the analog signal in analog form; applying an offset to analog signal in analog form; filtering the offset signal in analog form; and emitting, by the signal emitter, the filtered signal.

1. A playback device comprising:
a signal detector adjacent to a first side of the playback device; a signal emitter adjacent to a second side of the playback device; a processor; and memory having stored thereon instructions executable by the processor to cause the playback device to perform functions comprising: detecting, by the signal detector, an analog signal from a first device; amplifying the analog signal in analog form; filtering the analog signal in analog form; applying an offset to the filtered signal in analog form; and emitting, by the signal emitter, the offsetted signal to a second device, wherein the offsetted signal is emitted to cause the second device to receive at substantially a same time the analog signal and the emitted signal as a single signal.
