 Detecting zero-crossings 
 in noisy signals is a classical 
 problem that has been researched for over a 
 century. We compare the accuracy and speed of 
 our approach with available methods in the literature 
 using different types of noisy signals, 
 as well as showing sensitivity studies that 
 consider the sampling frequency (SF), and 
 Signal to Noise Ratio (SNR). Our results show 
 that TSP can be directly applied to unfiltered 
 signals with moderate to high noise levels 
 for finding the zero-crossings. In contrast 
 to many existing tools, our approach does not 
 require any complex analog circuitry, iterative 
 solvers, or filtering.\n\n
