Abstract—This paper presents a new method which could reconstruct a signal by using the samples of derivative signal. Using this method in Asynchronous Level Crossing converters which introduced non-uniform samples, leads to a significant reduction in number of samples which are needed to reconstruct a signal. This method is beneficial for signals which could be estimated as a polynomial function in some part of its domain. The time instances of each sample should be sent too.

Index Terms—Analog to digital converter, asynchronous level crossing converter, non-uniform sampling, signal reconstruction.
