In this work we raise the question of noise suppression by statistical analysis of Analog-to-digital converter (ADC) data vs. Time-to-digital converter (TDC) sampled data. The current technology options are identified. We analyze realistic scenarios through computer simulation and conclude that TDC has the same statistical potential as ADC, but current devices offer insufficient memory depth for long range, low signal to noise ratio laser range-finders’ applications.
