-What happens if we make one of the ring oscillators slower? The C-element will wait for the //slower// of the two oscillators before changing its output. Hence, the cycle period of this particular circuit will be determined by the slowest cycle of gates in the circuit. This simple example and intuition can be translated into a [[https://csl.yale.edu/~rajit/abstracts/exactmulti.html|rigorous mathematical framework]], where we can show that an asynchronous circuit will exhibit periodic behavior.((S.M. Burns and A.J. Martin. Performance Analysis and Optimization of Asynchronous Circuits. Proc. ARVLSI, 1991.))((Wenmian Hua and Rajit Manohar. Exact Timing Analysis for Asynchronous Systems.
