We present a scheme for simple oversampled analog-to-digital conversion, with single bit quantization and exponential error decay in the bit-rate. The scheme is based on recording positions of zero-crossings of the input signal added to a deterministic dither function. This information can be represented in a manner which requires only logarithmic increase of the bit rate with the oversampling factor, r. The input band-limited signal can be reconstructed from this information locally, and with a mean squared error which is inversely proportional to the square of the oversampling factor. MSE = O (l/r 2). Consequently, the mean squared error of this scheme exhibits exponential decay in the bit-rate.
