A Polarity Optimization Algorithm Taking Into Account Polarity Conversion Sequence [PDF]
IEEE Access, 2019 The polarity conversion sequence directly determines polarity conversion efficiency and then affects polarity optimization efficiency. However, few studies have focused on the polarity conversion sequence problem of Reed-Muller (RM) circuits. In this paper, we propose a continuous Hopfield neural network (CHNN)-based polarity conversion algorithm ...

Rectangular to polar conversion
Electronics Letters, 1983 For the conversion of complex numbers from the rectangular form a + jb into polar re10 = r ? ?, it is required to evaluate r = ?(a2 + b2)and ?= tan?1 (a/b). A simplified method is presented here for evaluating r and ? from a and b using a simple analogue circuit that operates as an inverse sine function module.
