Abstract:
Shuttering eyewear used to view 3D imagery and/or dual-view images may utilize an IR receiver filter with moderate to wide bandwidth to pass data sidebands of an on-off keying signal while strongly rejecting nearby interference sources. Filtering of the signal may be achieved via a circuit for passing data sidebands of infrared signals. The circuit may include a band pass filter with a low value of Q operable to filter out a first type of interference signal from a signal, a plurality of mixers operable to receive the signal from the band pass filter, wherein the plurality of mixers down converts the signal to baseband signals, and a plurality of low pass filters operable to receive the baseband signals from the plurality of mixers, wherein the plurality of low pass filters rejects a second type of interference.
