Abstract:
1. A method for encoding and decoding of signals using a) a transmitter capable to generate an optical signal when subject to an electric signal, and b) a receiver capable to generate an electric signal when subject to an optical signal; wherein a multi-level encoding of optical signals is used, wherein said transmitter is capable to generate wherein said second duration is longer than said first duration, and wherein said transmitter is fast and said receiver is slow such that a response time of said receiver exceeds said first duration of said optical pulse generated by said transmitter; and wherein an electric signal generated by said receiver as the response to the optical pulse having said first duration has a first amplitude, and wherein an electric signal generated by said receiver as the response to the optical pulse having said second duration has a second amplitude, and wherein said second amplitude is larger than said first amplitude.
