摘要： A wireless binary coded optical data receiver receives the binary encoded data via a photodiode. The binary encoded data is then supplied to the primary winding of a transformer and thus coupled to the secondary winding of the transformer. The secondary winding is coupled to a transimpedance amplifier wherein the transimpedance amplifier buffers the received binary encoded data. The buffered binary encoded data is then amplitude limited by a limiting circuit.

In the transceiver, an absence detector receives a transmitted signal, determines an absence of the transmitted signal, and passes the absence to an activity detector in order to differentiate between a reflected signal and a received signal in a half duplex system. The activity detector receives the received signal and determines an operation time signal in which the received signal is absent.

From the count, the amount of charge that must be replaced can be determined. As the charge is replaced the count is decremented.

摘要： Binary encoded data may be detected in a stream of data, by first detecting data transitions. From the detected data transitions, a first pulse is generated when successive data transitions are detected within a predetermined period of time and a second pulse is generated when successive data transitions are not detected within the predetermined period of time. The first and second pulses have the same duration but the amplitude of the first pulses is half of the amplitude of the second pulses. The first and second pulses are filtered by a bandpass filter and compared with a predetermined threshold. When the filtered pulses are above the predetermined threshold, the received stream of data is binary encoded data. When the filtered pulses are below the predetermined threshold, the received stream of data is not binary encoded data.
