Abstract: A data slicer including detector means connected to a signal input for detecting the presence of data clock pulses on an incoming signal. Generator means are connected to the detector means for generating a sampling pulse during the time that the presence of the data clock pulses is detected. Filter or delay means are connected to the signal input for establishing the mean level of the incoming clock pulses. Sampler means are connected to the filter or delay means for sampling the mean incoming signal level when established by the filter or delay means during the sampling pulse interval and for storing the sampled signal. Comparator means having a first input are connected to the signal input and a second input connected to the sampler means for receiving and comparing the incoming signal with the sampled signal stored in the sampler means to effect slicing of the data from the incoming signal.
