    • Analog signals can be fully encoded as an asynchronous time sequence generated by a time encoding machine. With knowledge of the parameters of the time encoding machine, the asynchronous time sequence can be decoded using a non-linear time decoding machine. Such a system can be extended into an encoder/decoder in which a signal is processed in M separate channels. An input signal is applied to the encoder where the signal is provided to an M channel encoder circuit including a filter bank having a total bandwidth partitioned among M adjacent or overlapping filters. Each of the M filters are coupled to a corresponding one of M time encoding machines. The encoder output is represented by M sets of time encoded trigger values. The input signal can be recovered from the M sets of time encoded trigger values by applying the trigger signals to a corresponding M channel decoder which includes M TDMs and filters. The TDMs recover the continuous signal from each channel. The filter outputs xm are then amplitude scaled sm and are combined to recover the input signal. By partitioning the signal bandwidth into M channels, the average pulse rate from each TDM is substantially reduced.

    • Analog signals can be fully encoded as an asynchronous time sequence generated by a time encoding machine (TEM). With knowledge of the parameters of the time encoding machine, the asynchronous time sequence can be decoded using a non-linear time decoding machine. In one embodiment, the non-linear time decoding machine generates a set of weighted Dirac delta functions centered in the intervals of the asynchronous time sequence of the time encoding machine output. The weighting of each of the delta functions is determined by the parameters of the TEM as well as the values of the time sequence. The generation of the series of delta functions is a nonlinear operation (500, 510, 520). The input signal can be recovered from the series of weighted delta functions by (530) applying this series through an impulse response filter.
    • 模拟信号可以被完全编码为由时间编码机(TEM)生成的异步时间序列。 利用时间编码机的参数知识,可以使用非线性时间解码机对异步时序进行解码。 在一个实施例中,非线性时间解码机器生成以时间编码机器输出的异步时间序列的间隔为中心的一组加权的Dirac delta函数。 每个delta函数的加权由TEM的参数以及时间序列的值确定。 一系列delta函数的生成是非线性运算(500,510,520)。 通过(530)通过脉冲响应滤波器应用该系列,可以从一系列加权的增量函数中恢复输入信号。
